ohhh anon you have so good questions oh my gishgosh
gaara can’t sleep too much so he kinda rises with the sun and wanders around the house aimlessly until his sibs wake up too. doesn’t like coffee so he drinks green tea for caffeine and eats super little, like a croissant or something like that.
temari is kinda similar, but she wakes up around 9. likes coffee with milk, but would rather drink tea too. believes that breakfast is the most important meal of the day so eats plenty and very healthily.
kankuro is a night owl and also fucking lazy, so he kinda needs to be dragged out of bed around 3 pm. he doesn’t have a fixed diet, just eats whenever and whatever he feels like to. loves coffee tho, and will drink it at midnight too
