Books that really capture the inner and outer world of childhood (like how young people feel, think about themselves and the world, what motivates them, etc.)?

Was writing a short story and it's about a family with kids and it occurred to me I've forgotten how kids see the world. Like how they feel about things, what they think of adults in their lives, what matters to them and motivates them, how think of the future, etc.

Any good books that really capture the inner and outer world of youth?
