I'm Gonna Like Me: Letting Off A Little Self-Esteem by Jamie Lee Curtis
I love this upbeat picture book! It's a great one to read with little ones, and even the big ones like it. There are lively illustrations, and it shows kids that it's ok to like themselves even when they make mistakes or don't quite fit in. There's also a helpful PDF for teachers that parents can use to reinforce the message of the book. And here's a mini printable version you can have them fill out about themselves. Have fun!
