(WHIMSICAL MUSIC) (BIRDS CHIRP) (CHILDREN LAUGH) Brothers and sisters. Oh, Mabel. High five! Love them... You won't fall off. I'll keep you safe. ...or loathe them,... (WAILS) Then he just grabbed my arm and threw me. ...there's no escaping them. Hey! If you want her, you can keep her. GROANS: Be quiet! For those of us who have siblings ` and 80% of us do ` it's probably gonna be the longest relationship of our entire life. It's British summertime. And six younger siblings are going camping... Boo! ...with their big brothers and sisters. I'm Jack. I'm George. What does it mean to be the youngest? It's no fair, because they have bigger brains. Here to find out, and observing their every move, are scientists. Sibling relationships can be more influential than relationships with peers or even with parents. Chaim, give me the bucket! No, no. I-I'm gonna do it. The way we resolve conflict with our young brothers and sisters can predict our conflict resolution styles as adults. Sorry! Nah. (GROANS ANGRILY) There's no boundaries here. They're out of their comfort zone. This might bring these brothers and sisters close together, or it might elicit some explosive conflict. Are you ready? (WHISTLE BLOWS) Pull! Brothers and sisters, side by side, in the wild. (CHILDREN YELL) Copyright Able 2017 (BIRDS CHIRP) (WHIMSICAL MUSIC) Six families are about to start their camping weekend in the woods. (LAUGHS) Ah, found our tent. Yeah. It's here. READS: Charlotte and Harry. First to arrive is 5-year-old Charlotte with her 7-year-old brother, Harry. Whoa! Look at that. What do you reckon? BOTH: Good. Ew. Go on these two parts. Ew, Chaim, my feet. We're fine. Ew. 5-year-old Zohara is here with her big brother, Chaim, who's 7. K, now we're not going to go together. OK? We're gonna separate. Oh, here! Here! READS: Chaim and Zohara. Boo! MAN: Why do you think people like to go camping? Mm... I've got no idea. Yay, I found it. Over the next three days, the siblings will take part in a number of tasks set up by our scientists to observe the dynamics of their relationships. Look! Look! A fascinating aspect of sibling relationships is their enforced nature, and that makes it a great place to take risks. (BLOWS) You can have conflict. Harry! And conflict can be a good thing. What? Practising through those social interactions is gonna be really helpful for children in later life. BOY: There's a real fire! It's really muddy! 6-year-old George has come with his 8-year-old brother, Jack. Jack and George. George and Jack, more like! Whoa! Is this what we're living in? Yep. Is that what we're`? Yes. It's camping, George. MAN: Is there anything scary in the woods? Um, the only thing that's scary in the woods for me is maggots. BOTH: Hi! Hello. My name's Kash. I'm Jack. I'm George. 6-year-old Kash is also a younger brother but with much older siblings ` in their teens. What's your name? Chaim. Ky-am? No, Chaim. Ky-am? Ch-aim. Hi-am? (LAUGHS) As the boys bond over a game of football, little sisters Charlotte and Zohara are quickly forgotten. Should we make, like, a secret hideout? Yeah. Do you wanna make a den? Yeah. Which one? Come on! At this age, these younger siblings are really wanting to assert their own identities. They need to fight for their place within the family, and over the next few days, are they going to get elbowed out in place of peers, or are they going to make their mark? Boys only. Hey! Get back. Get back. No girls allowed. No girls allowed. GIRL: Whaaat? Oi! Are you brother and sister with her? Yeah. Really? Sadly. But` (GIGGLES) MAN: What do you normally do if Harry doesn't wanna play with you? Uh... She always te` Well, she always tells Mummy and Daddy. Sh` She` She always tells Mummy and Daddy of everything I do. Not everything. Yeah, you do. Only if it hurts me. Charlotte and Harry live in East Sussex with dad Nick, who's a lecturer; psychologist mum Natalie; and baby sister Alice. NICK: Harry and Charlotte's relationship is close. They spend a lot of time with each other, and they live the ups and downs together. And so if they're having fun, if they're sad, they're doing it together. In the car yesterday, Harry kept punching me. And Charlotte was crying. And Harry was. I wasn't crying! Yeah, you was. No, I wasn't. LAUGHS: Yeah, you was. No, I wasn't. Yeah, you was. No, I wasn't. NATALIE: But they fight as well. Yeah, you was. And Charlotte will always be the one that backs down. Like, if you've got a packet of sweets, and, you know, there's 15 in the packet, it will be, like, seven-seven each. It'll be, 'Who gets the last one?' And Charlotte will normally be, 'It will be all right, Harry. You can have it. You can have it.' She is like that. Six! No. It wasn't. It was five. Yeah, I saw. No, I saw it. No. You saw` You saw` You know, like, sometimes you, like, see another dot. Harry likes to win more than` than Charlotte does. Um, whenever they're playing a` a game, he'll often play it for the competition rather than the fun, whereas Charlotte, I think, is much more focused on the fun. Yeah. I will let you have that just this once. Charlotte, she is who she is. She's very confident in herself. And it's kind of like, 'If you like me, you like me. If you don't, you don't.' (WHIMSICAL MUSIC) Ahhh. (GARGLES, SPITS) (LAUGHS) It's day two on the campsite. MAN: Hello, hello. Oi, oi! Hello. Some of the children have left their parents behind to begin camp activities with teachers Kate and Ollie. OLLIE: Uh, OK, George, what's the name of your brother? Jack. And, um, what's the best thing about Jack? His farts are really smelly. (LAUGHS) He always burps at the dinner table. Yeah? And, um... And what are his bad points? Uh... Also here are 7-year-old Cuba and his big sister, Mia, who's 9, and 6-year-old Elouisa with her 5-year-old brother, Sebastian. Guess what. He had a slug in his shoe! For their first task, the children will be divided into groups to make a sculpture from items found in the forest. We've got sticks, OK? And we've got twine, and we would like you to make something. George is working with his big brother, Jack, alongside Charlotte and Harry. CHARLOTTE: Maybe we should` GEORGE: Let's decide what we're going to build. A nest! Come on! Or a little birdhouse! A nest! That's good. On hand to observe every moment are scientists Professor Paul Howard-Jones and Dr Sam Wass. First, do a knot, and then tie the string around. Older siblings often tend to be dominant and to insist on setting the mood in any given situation. So we've devised this task to see how good our older siblings are at letting the young ones play a part and also to see how good the younger ones are at finding a role for themselves. KASH: What are you making? We're making a birdhouse and a bird's nest. I'm doing the nest. GEORGE: Yeah. Yeah. No, it's a bird's house too. Didn't you know that? Oh. Oh. Hey, let's start putting some hay in, yeah? No, Charlotte, put them down here. But aren't we gonna start building this up? For the nest. But not yet, Charlotte. Do you want me to sprinkle of this on here? No. I'm fine. What about...? It's OK! It's OK, George. SADLY: Oh. MAN: How does it make you feel when Jack ignores you? Uh,... quite sad, and, uh... But it's still` I still wouldn't` don't give up. Jack, for the sun, we could, like, get a stick and attach a flower to it, and it could be the sun. I got a good idea for the sun. Jack's not listening, so he's taking it to Harry. A flower on top of it, and that could be the sun. See, the thing is George would love to have more attention from Jack here. He'd love to have more interaction. Actually, Jack's had enough, and that's why Jack is pushing him away and finding him a little bit irritating. It was a good idea I thought George had. Let me help! (GROANS) Oh! I like being on my brother's team. Why? Um, because... I don't know. It just feels right being with my brother. 6-year-old George and 8-year-old Jack live in Essex with dad Kev, an electrician; full-time mum Leanne and baby sister Rosie. Jack` Which one blue do you think it will be good for a sea, Jack? Ooh! KEV: George does look up to Jack, especially with things like arts and crafts. George thinks that Jack's is better and that he can improve on it by looking at Jack's work. (YELLING, LAUGHING) LEANNE: They do really get on well, but they both are very competitive. Ow! I suppose a lot of that comes down to they're quite close in age ` there's only two years between them. Ow! MOANS: I hate you. It is a rollercoaster ride. They will scream and shout at each other and tell each other, 'I hate you.' 'No, I hate you.' Jack! And then later on that evening, you'll go upstairs, and George has got out of his bed, and he's got in bed with Jack, and they've gone to sleep together. That's them. That's their relationship. WHISPERS: I wish you'd stop. (BLOWS RASPBERRIES) Aargh! I just hope as they get older, they stay that close ` (LAUGHS) You blinked. you know, even if they're in their 20s and they take their shirt off and have a little punch-up then, like they do now, then they hug it out or` and they get on. It's important to me that they're close. Why do I suggest that you make up with each other? Hmm. (ALL LAUGH) Right, boys and girls, you've got a couple more minutes to finish off your, um` your projects. With the clock ticking, it's all hands on deck. Good. Jack, you keep building the floor. You make the shape. Keep building that house. You're doing very good. Oh, that's nice. Yeah. He's like George the foreman going around, 'You're doing well.' 'You're doing very good.' 'Keep up the good work.' Guys, you're doing great! Keep getting that fern, OK, Charlotte? Yeah. What we're seeing here with George is typical younger sibling behaviour. He's experimenting with different ways of trying to access and get into this activity, and he's hit upon this idea of being a cheerleader ` and it works. OLLIE: So, Jack, what have you`? What have you and George made? We've made the nests, and we've made the outlines. OK, so it's` It's` And we made the landing pad. It's funny, isn't it? Cos they're so proud of what they've done, and it's just, like, a bunch of hay on the ground. It's not just a bunch of hay on the ground. In their eyes, it's so much more. It's a work of art made from found objects. It's pretty good work, isn't it? Well done. That's really, really good. For 10 minutes. For 10 minutes, I think that's brilliant. George and Jack have done a pretty good job of regulating their frustrations in this task. But we know that siblings with an age gap of around two years tend to have the most conflicts and rivalry in their relationships. So we'll see how long this holds up. (GIGGLES) 1 (MAN) THINKS: 'Man, Steve is really smelly. 'Oh, sort that out. 'He smells like a teenager's watch band. 'I look like Tintin. He's cool ` Tintin. 'How do you tell a guy he smells? Do you have a smell intervention? 'Maybe just wait for his birthday and just go, 'Happy birthday, Steve!' CAR HONKS 'Ooh, sorry! 'And for a present you give him a deodorant and say, "Oh, here's a nice necklace. '"It's actually a car deodoriser. Pop that round your neck, mate."' TYRES SCREECH, CRASH! CAR RADIO CONTINUES PLAYING BREATHES LOUDLY (UPBEAT ACOUSTIC MUSIC) Yes! It's early afternoon on the campsite. Hey, do you want a piece of chocolate? No, I'm vegan. What? Vegan. Vegan? Yeah. Vegan means I don't eat any meat or cow milk or anything. I just eat, like, oranges and... spinach and stuff like that. You already can have at least one piece of chocolate. I can't. Yeah, you can. I can't. BOY: Jack! The next activity for the children is an obstacle race. The idea of this is to go in your pairs with your brother or your sister. There are two rules ` if you touch the ground at any point, you have to start again. The second rule is you have to take with you, between the two of you, a bucket of water. I'll go first. Because I'm fastest. And you have to put the bucket of water on the crate at the end, OK? And then you have to come back. OK? So, Charlotte and Harry, if you come and stand here. And Chaim and Zohara, you stand there. Zozo` Uh, wait, Zohara. I'm going` You carry the bucket of water. I'll carry it. You carry the bucket of water, I'll go in front` No, I` I'm up the front. I'm in the front. Zohara, move. I` I` But, Chaim, I'm gonna do the thing. No, no, I am. I am! Typically, siblings argue up to eight times an hour. So this next task is going to be a challenge. In order to succeed, the brothers and sisters have to work together. Three, two, one. Go! Go! Zohara. Zohara, quickly. Go, go, go, go, go. ZOHARA: You're going too fast. Zohara, quickly. Get on! You're going too fast. Get on! You're going too fast. Oh, Zohara! Come on. Keep...on. OLLIE: Touched the ground! Go on! Back you go! Chaim! Rules are rules, so it's back to the start for Chaim and Zohara. Zohara! Because I need to go first. No, you don't! I need to. Chaim is not thinking about Zohara. What's nice about this task is you're as good as the weaker partner. That's why it's a good task. Chaim, give me the bucket! No! No, I-I'm gonna do it. K. Oh! Back to the start! Go, go, go! Brothers and sisters fight so much because they compete over scarce resources ` crucially, parental attention but also who's going to be in control. This conflict plays out in everything they do. MAN: Do you two make a good team? Yes. No. Yes. 5-year-old Zohara and 7-year-old Chaim live in North London with solicitor mum Tiffany; dad Moshe, who runs his own business; and 11-year-old sister Maya. (GIGGLES) TIFFANY: Chaim is a big personality. He's a strong character. Zohara's always trying to keep up. She` Usually, she want it her way, because she is the baby, so she always get her way. Mummy, Chaim's being annoying! They argue about everything. Stop it! You start. No, you. You. No. You. You! They both want to stand in the same place; they both want to use the same toothpaste at the same time; who's gonna go up the stairs first ` everything! Four! No, that doesn't go together. That doesn't make a four. Sometimes Zohara can't compete with Haim or understand, maybe, the situation or find a solution. Then she will lose her temper. OK. ANGRILY: Stop giving me reds! Stop giving me reds! Stop giving me reds! Zohara ` bless her ` looks like a fairy. But she's n` (LAUGHS) She's as tough as Chaim. Stop giving me reds! (CRIES) SOBS: She got it in my eye. So? (CRIES) Chaim, play popcorn! As much as they compete with each other, they love one each other. Waaah! Ah! OK, I win. It's amazing to see them playing together, but then you` you see them fighting together, and then` (LAUGHS) It's a` It's a love and hate. CHILDREN CHANT: Jack and George. Jack and George. Chaim and Zohara look on as the other pairs complete the course,... (WATER SLOSHES) OLLIE: Brilliant! ...before they're given a chance to better their time. Go slowly. Go! Go, Zohara. Slow and steady. Slow and steady, Zohara. Chaim's saying that? Chaim is giving advice. Zohara, slow and steady. Well done, Chaim! All right. Now you get back, Chaim. KATE: All the way back. CHAIM: Now, I'll get back. Zohara, get on here. Look, he's really taken to it now ` that moment where Zohara said, 'You need to help me with this, Chaim,' and he's really been very sensitive, actually. That's really good. OK. St` Get off. Good. He is demonstrating really nicely how the relationship with a sibling can be full of conflict, and yet, when needs must, it can be a very cooperative relationship. Yeah. Your best friend and your worst enemy, all in one. Chaim! Chaim! Chaim! OLLIE: OK, stop the clock. I've got my little sister. MAN: What's better ` being a big sister or a little brother? I'm not little! (CHUCKLES) It's better being smaller, because you don't have to do all the work when your big brother has to do all the work. I wanna be the oldest. I don't wanna be the youngest. Boo, doo, doo... Waaah! Mwah! (BLOWS RASPBERRY) Ooh! I like being young cos I won't die as fast as Mia. . (WHIMSICAL MUSIC) Ooh. Oh, Jack, help me here! I'm in a shoe battle! The great British summertime means some of the children have gone to play inside. They've been set a nature quiz, with the older siblings on one team and the younger siblings on the other. KATE: So, move yourselves into your teams so you've got oldest on one side, youngest on the other. Whoa, whoa, whoa. (HUMS) It's no fair, because they have bigger brains because they're older than us. George is absolutely right here. The elder siblings' brains are bigger, and this task is inherently unfair. But how do the younger children manage when they encounter a situation that they encounter all of the time in real life? How do they cope when they're competing at a disadvantage? You need to choose one team leader, please. JACK: Me. Me. Oldest gets to be in the thing, and I'm the oldest. WHINES: Me. Me. If you be it,... Me? ...you have to listen to us. OK. Shall we do rock paper scissors? That's fair. OK. Wait ` coconut, coconut, crack. That's easy. I don't know that. I don't know that. Oh. Put your hands like this, guys. Yeah. Coconut, coconut. Ow. Coconut, crack. So... Can youse just choose?! Coconut, coconut, coconut, crack takes forever! Eh. Just choose! OK, let's do rock paper scissors, then. KATE: All right, I'm gonna have to ask you guys to choose a leader soon. Just be it already! Just` Let's do rock paper scissors. No, it's` That's fair. GROANS: Be quiet! KATE: Do you have a team leader? Yes. Me. All right. So, George, you're the team leader, and Chaim, you're the team leader. Yeah. OK. So, I'm going to be looking for really imaginative, really creative answers to my questions, OK? So would you like to come up with a team name? Mind Breakers. I know. Should we call it the... Storm Creators ` that's the best. All right, what's your team name? Storm Creators. Storm Creative. And...? Mind Breakers. Mind Breakers. All right. Can you name three creatures you've seen since you've arrived here? Slug, beetle and... ...ant. Caterpillars. (GASPS) Slugs. Slugs. I've seen a rabbit. OK. I'm going to take answers from Storm Creators first, please. OK. Slugs, caterpillars, ants, rabbits. All right. And... We've got red` red ants, slimy slug, beetle, rabbit, big ants, (STAMMERS)... uh, a small ant. Yeah, I don't know why he wrote the same things. So I'm gonna give each of you a point for that one. By the last round, the older team have taken a three-point lead. All right. This is the last question. What do you think a slug tastes like? Wha`? What? Salty. Slimy. Slimy. QUIETLY: Slimy, disgusting. Slippery, slimy. Should I write them down? No. KATE: OK. Mind Breakers. Sour, salty,... ...disgusting. ...disgusting, slimy, horrible, juicy, sticky... And that's it, I think. ....and... I think he's just thinking of one. ...eyeball... horribility. Eyeball horribility. All right. Thank you very much. All right, Storm Creators. Slippery and slimy,... WHISPERS: Slippery-slimy. ...soft, juicy, dirty and sticky. Ooh. Now, this is a tough one. We won, right? OK, so, two points... to Mind Breakers. Yes! And Storm Creators, I'm gonna give them three points. Yeah, we still won. Yeah, we still won. So three for them. We still won. The winners of the quiz are Mind Breakers. Yeeeahhhh! So, Mind Breakers, we've got... one for you. Thank you. I like it. Nice. OK, so, Storm Creators, should we give them a round of applause? Yeah, so, well done, guys. BOYS: Thank you. Thank you. Very close. It was very tight. Charlotte has good emotional regulation. She's not fazed by this defeat. George, on the other hand, shares more territory with Jack. It's a more competitive relationship. I think he feels a sense of defeat and of injustice quite strongly. Sometimes when your brother wins, you feel like you should get a prize too. Um, but you get that feeling that you need to, um, cry. Get Mia! (LAUGHS) I got her! Hey! Hey! Hey! Hey! OLLIE: OK. Everyone sit down. We're gonna play tug of war. And we're gonna pick teams, OK? So, Kash, you're captain of one team. Jack, you'll captain another. Uh, I choose you. Aw! I wanted to be with my brother. Win some; you lose some. Boys and girls, are you ready? CHILDREN: Yes! Take the slack. Wrap it around you! Wrap it around yourself! Three, two, one. Go! (WHISTLE BLOWS) (LAUGHTER) We're winning! (GROANING) BOY: Our one's winning! (YELLING) You are going down! (WHISTLE BLOWS, CHEERING) We won! We won! We won! High five. Fist bumps. Victory for George's team ` and it's lollipops all round. Can I have a sweet? Yeah! Mine! Sorry. (GRUNTS, CRIES) Can you stop it?! George. (CRIES) George, come here. (BREATHES SHAKILY) Why did you do that? GROWLS: Get out. (CRIES) Why are you angry? Just tell us. We're your friends. I thought that because his team lost, he didn't get a sweet, and then he just grabbed my arm and threw me. I don't care about the prize or anything. It's just George being a... Don't worry, Jack. Don't worry, Jack. Being two brothers intensifies the conflict between George and Jack. Research shows that boys with older sisters are 35% less competitive than boys with only older brothers. GEORGE: Pass! (YELLS) George! No. No. George. Handshake! No. Sorry! Mm, nah. (GROANS ANGRILY) (SHOUTS) (SPEAKS INDISTINCTLY) MAN: How many times a day do you argue? Um,... about five. Or maybe 10. Jack. What? Sorry. Sorry. Bye. Sibling conflict can teach children about negotiation skills, about relationship repair, and, luckily, many of those brothers and sisters have a love-hate relationship ` so that one minute they might be fighting, but the next minute, they're loving each other. Hurry! Hurry! Come on! Come on! I love him a lot, even though we argue a lot. Tricked ya! I'm not on your team. I'm on Jack's team. Ha! Jack, go long! Get it! (WHIMSICAL MUSIC) OLLIE: Morning, everyone. CHILDREN: Morning. The brothers and sisters are halfway through their camping trip in the forest. Did you all sleep well? BOY: I had a slug in my shoe. BOY: And I had a slug on my pillow. Lovely (!) (CHILDREN CHEER) High five. This morning, as a warm-up, teachers Kate and Ollie are holding a dance contest. You'll be partnered with your brother or sister, and there will be a prize for the best pair. Aaand up and dance! Come on! (CHILDREN CHEER, UPBEAT MUSIC PLAYS) Siblings Harry and Charlotte are first on their feet. Take the space, Charlotte. Take the space. Come on! Up! Everyone up! Have a little boogie. Chaim, are you gonna give it a whirl? (UPBEAT MUSIC CONTINUES PLAYING, CHILDREN CHATTER) Oh, here we go. We've got some robots! (SHOUTING, LAUGHTER) At the moment, Charlotte and Harry are smashing it! Come on! Chaim, there's no way you can win if you're not dancing with your sister. (ZOHARA SQUEALS) (CHUCKLES) Dancing, not murdering. (BOTH LAUGH) (LAUGHTER) (CLAPS) Really good! Really good! All right. So, look, this is for dancing in pairs. I think, really, there's only one winner, because they were up first, they danced the longest and the hardest. The winners are... Charlotte and Harry. (APPLAUSE) Yeah! Really good. BOTH: Thank you. HARRY: Yay. Whoo-hoo! Take the dancing squirrel. And well done, Charlotte and Harry! Are we allowed to take this home? That's why you should've danced. You` You could've got first if you, uh, could've danced. BOY: Get off. My go. (YELLS) My brother's quite annoying, because he always likes doing breakdancing instead of, like, normal dancing. But I don't like dancing. (SQUEALS) It's her! (SQUEALING, LAUGHTER) When we do stuff that we're supposed to do and we might win a trophy, she doesn't do it. And I try my hardest, and Zohara's just, like, sitting there like this. I'm doing it! One of the things that younger brothers and sisters try to do is to self-differentiate. They'll look at their elder sibling and try to make themselves a bit different to them. Why do they do this? Well, it's to avoid direct competition. So what Zohara's doing here is showing quite a lot courage. She's asserting her own independence. She's saying to Chaim, 'No. Dancing's your thing, but it's not mine.' CUBA: Only the boys go over here, don't they? This is the boys' place. Boys make friends. Girls make friends with girls. I hate girls ` except my mum and the teachers. (LIGHT-HEARTED MUSIC) BOY: Look, look, look. It's mid-morning. And for today's obstacle race, it's sibling versus sibling. OK. First up, Chaim and Zohara are gonna race against each other. OK? So go and line up by the tree, please. Well done, Zohara. Unlike the other task, where the brothers and sisters had to work together, in this race, one's gonna win, and one's going to lose. This physical disadvantage is what younger children face every day of their lives. How are they gonna cope with that? Chaim and Zohara, that difference in size is so marked. (SOBS) Go! Oh, poor Zohara. She can see what's coming. She is at such a disadvantage. She knows Chaim's going to win. Ready? Three, two, one. (BLOWS WHISTLE) ALISON: Oh, she's still competing! SAM: She's still doing it. Good on her. (CHILDREN CHEER, YELL) KATE: Under you go! Zohara, quick! 10 seconds on the log! QUICKLY: One, two, three, four, five, six, seven, eight, nine, 10. (SUSPENSEFUL MUSIC) OLLIE: Oh! Chaim. Really good! Really good! It isn't fair. (CRIES) Go on, Chaim. Give her a hug. Come on! (CRIES) Many children at this age will show what can appear to be an astonishing lack of empathy for their younger sibling. And it probably comes down to competition. You spend so long competing with your sibling, mutual understanding often goes out of the window. After a snack break, the teachers change the rules to give an advantage to the younger siblings. So, we're gonna give the younger brother or sister a head start. OK. Ready? Three, two, one. Go! (WHISTLE BLOWS) Quick! Go, go, go, go, go! (UPBEAT MUSIC) We shouldn't be afraid of sibling competition. It can teach them resilience, emotion regulation. It can also drive them to do their very best. Get it in the basket, Zohara! EXCITEDLY: Yeah! Zohara won. Big cheer for Zohara! (APPLAUSE) KATE: Well done, Zohara! MAN: Because Chaim's bigger than you, does that mean he's better at everything? No, because sometimes, uh, the littler one can` uh, can` can win. OLLIE: OK. Last race. Last race, George and Jack. If you win, I get a prize, OK? You give it to me. OK. But, um, you have to give me your prize back. Yeah, I'll give you the cone prize, OK? Yes, I love that one! Three, two, one. Go! (WHISTLE BLOWS) Come on, George. Focus. (UPBEAT MUSIC) (CHILDREN CHEER) Ooh! You all right, Jack? (CHILDREN CHANT) (GROANS, YELLS) QUICKLY: One apple, two apple, three apples, four apples, five apples, six apples, seven apples, eight apples, nine apples! (YELLS) JACK: He's already won, hasn't he? EXCITEDLY: Yeah! Keep going. Keep going, Jack. KATE: Keep going, Jack. Really good job. Well done, George. (PANTS) (WHISTLE BLOWS) Where's the prize? (REFLECTIVE PIANO MUSIC) When the younger one wins, the power relationship between older and younger sibling is disturbed. (SOBS) Because the basic framework of the relationship has been given a wobble, it can be very distressing and humiliating for the older brother or sister. OLLIE: OK. Well done, Jack. Good stuff. That was really interesting. George was looking happy, Jack came up, George was looking at Jack, seeing how upset Jack was, and you really saw George's facial expression change to mimic Jack's. Mm. They're definitely quite empathetic, those two brothers. OK, brilliant. Well done. Really, really, really, really good. OK. Now we're gonna give the winners of each of those races a prize. And the prize is gonna be two pieces of chocolate. If you wanna share it with someone, you can. The chocolates here are a classic restricted resources task. It's a way of finding out who is most important to these children. Do they wanna keep sweet their friends or their siblings? So, Chaim and Zohara. And a big round of applause to Zohara. (APPLAUSE) Really good. Really good. Right. OK. So we've got one, two. Who are you gonna give your second one to? (HUMS) My friend. Who's your friend? Charlotte. Oh, Zohara! (LAUGHS) The last race was between George and Jack. And a big round of applause for George! Well done, George. Whoo! (APPLAUSE) There you go. Thanks. Good stuff. SIGHS: Thanks. He has definitely favoured family over friends. George didn't think about that for a second. No. What George is thinking here is, 'I know that Jack's disappointed, 'and I'm going to give him this chocolate bar to try to sweeten the pill.' I think this could show that he's quite socially sophisticated for his age and smart enough to figure out how he can get out of this situation with the minimum repercussions. (PEOPLE CHATTER, FIRE CRACKLES) Give it a turn, George. I` Dad, I can do it. I can do it. Yeah, OK. You remember? Jack was sad because he lost against me, so I was thinking, 'You know what? I'll just give him a sweet.' I burnt another one! Two burns in a row! I think I was being a sore loser. MAN: What did you think when George shared his prize with you? Um, I felt happier then. That's ready, because it's about to drip, mate. Lovely jubbly. (LAUGHS) Lovely jubbly. Quick ` take it to Mummy while it's warm. Mum! Mum! It's ready! It's the last day on the campsite. We have big duvets in our tent. My bed is like` My head is facing` Cuba. Do you want a hot chocolate? You don't know what vegan is? Vegan means non-dairy. (WHIMSICAL MUSIC) Got two sticks. Later on, the children are in the forest, building dens. We have to keep on doing it, the whole layer, and then we've got ourselves a door. There'll be a prize for the best one. I'm in charge right? Because I have the flag, yeah? Nah. We're all in charge. OK. It's ended up as girls versus boys. Guys! Guys, guys, guys. You're doing it wrong. Left to their own devices, children at this age often divide along gender lines. Gender trumps sibling loyalty. I'm really strong. I can carry this all by myself. This is how strong I am. Harry! No, I had this stick first! Hey, buzz off! Only Sebastian, the youngest boy in the group, has chosen his sister's team instead. I found a good stick. They might be on the same team, but for George and Jack, old rivalries die hard. No! George, don't get that. No, George! A perfect fit. George! George! Even though it fits, it can get caught! (MOANS) Jack, that fits perfectly. Meanwhile, the girls have come up with their own plan. So, let's make one big seat, yeah? Yeah, that's great. What?! They're putting hay all over the floor! For the boys, this is the final straw. Sorry, mate. We have to take some of your stuff. We need all of your hay. Not all of it. All of it! No! This is our bits! CUBA: Get the hay! Nooo! This is our hay! You've got the stuff from inside, OK? Boys need some hay! The boys seem to have no problem here stealing from their sisters. They would never do that with peers. Again, you can't lose a brother or a sister, and sometimes that means that you can behave badly. BOY: Quick! Quick! GIRL: Not from inside! CUBA: Ow! We need it! Stop it! You! Kash! Look what they did to me! All right, guys. Time is up. So, I do want to see you all inside of your base camps. JACK: I think we can fit about three in! We can fit all of us. KATE: How's your comfort level, boys? Good! Yeah, really cosy. We can get a trophy. We're gonna get the shiny trophy. OK. So the winners... Cuba, we've won this. This team worked really, really well together. They just got on with it, and I liked the fact that they could all fit in. (GASPS) So the winners are green flag team. Yes! So, take care of the trophy. Let's put it in our house. Let's put it in our house. Whoo-hoo! (SQUEALS) We won! We won! They're putting it in their tent. No, no. I know where we can put it! There! Right there! We could just steal it, couldn't we? And then we'll just take us` it home. OLLIE: Guys, can you sit next to your brothers and sisters? (CHILD GROANS) With the camp nearly over,... Yeah! ...there's time for one final celebration. OK. Boys and girls, we've given lots of stuff for you to dress up in. In your brothers-and-sisters pairs, I want you to make yourselves into kings or queens of the forest. But we're brothers! We shouldn't be the queens. Yeah, I know. But you can be the kings of the forest, OK? And you can crack on. BOY: Yes! GIRL: Guys, OK, come on. BOY: I want this. I want this. I want this cape. I want this cape. GIRL: Why can't I have that? Over the past few days, we have seen, for these younger siblings, life is full of competition, rivalry but also a lot of nurturing, caring, cooperative behaviour. Uh, I've` (LAUGHS) (BOYS LAUGH) These relationships may seem at times to be dysfunctional, but that's exactly the way they're meant to be. Because, more than any other, our interactions with our siblings will teach us the tools for adult life. (LAUGHS) As younger siblings, we define ourselves against our older brothers or sisters. We learn the person that we want to become and the person that we don't. Harry. Mm? Can you help me? Yeah. He sometimes tries to kiss me. What? No, I don't! Yeah, you do. No, I don't. Yeah, you do! LAUGHS: Harry. Ohhh. Mia, can you put this cape on me? Yeah. I'm definitely a king now! MAN: What's better ` being youngest or being`? Being me. Being little. Being` Uh, being, uh, her big brother. She always copies me. Maybe around your head. Yeah! He's a karate master! Ha! Hoo! We're quite close, so it's good, because you can always have fun, and you can play with them. And, like, they're always behind your back, like George said. Mm, yeah, yeah. Very` Very cooperative, George` Jack. LAUGHS: I called you George! (CHILDREN ROAR, SHOUT)
