The best kid cartoon characters get a superpower no real child has: they never grow up.
Bart Simpson has been ten years old for more than thirty years, and that frozen childhood is a big part of why these characters stick with us for life.
This list gathers the most iconic kid characters in animation, from grade-schoolers like Bart and the Rugrats crowd to a handful of famous cartoon babies.
I kept it to actual animated kids, which meant cutting a few ringers: puppet characters like Baby Sinclair, live-action babies like Grogu, and a pig from Moana who is not a child at all.
Everyone below is the real, hand-drawn (or pixel-drawn) article.
