note: i know in the musical it describes some of them as kids already but these r my headcanons ! just putting that out there
usnavi: ALWAYS cleaning because he was one of those kids. he felt bad when he saw his parents or abuela working so hard at the bodega or at home, so he always offered to help.
sonny: when he was real little he liked to pull pranks. he still does as a teenager, but he calls those days his “mediocre days”. pranks like shaving cream and feathers, putting salt in coffee, etc. everyone had just about enough of him.
nina: always reading. she learned to read by 3 and never stopped. everyone saw potential in her. during the summer, she would wake up early, read the first half a book, help clean around the house for her parents when they got home, then read the second half of a book. very productive.
vanessa: she would run away a lot. growing up with an alcoholic mother, she didn’t really call the house she lived in “home.” she would come down to the barrio and hang out with nina or usnavi, or get hairdressing lessons from carla and daniela.
benny: he got in trouble with the law A LOT. of course it wasn’t that bad, since he was real little, but there wasn’t a week where he didn’t run from the police at least once. that’s how he met nina, in fact.
pete: like vanessa, he ran away from home a lot too. when he was 6 or 7, he fled home and went down to the subway station multiple times a week just to go and look at the graffiti on the walls underground. it fascinated him.
carla: she was that kid everyone loved. everyone wanted to be around her since she was so sweet, but she was taken advantage of easily and walked all over on a lot. baby carla :,(
daniela: she was the one who seemed cool. everyone wanted to be around her as well, so that’s why carla and her get along so very well.
