Okay kiddo, let me explain children's literature criticism in a way that's easy to understand.
You know how sometimes you read a book and you really like it, but other times you read a book and you don't like it as much? That's kind of what literature criticism is all about.
When grown-ups talk about children's literature criticism, they're talking about people who read and study children's books really carefully to decide whether they're good or not. They look at things like the story, the characters, and the pictures to figure out how well the book is written and whether it will be enjoyable for kids to read.
These critics might write reviews or articles about books they've read and share their opinions with other grown-ups who are interested in children's books. Sometimes they even give out awards to the best books of the year!
But the most important thing to remember about children's literature criticism is that it's all about helping grown-ups and kids find the best books to read. There are so many amazing books out there, and critics are trying to make it easier for families to choose the ones they'll love the most.
