What are baby words for the word autobiography?

There aren't really any "baby words" for autobiography, as it's a complex concept. However, you could try explaining it in a simpler way using terms a child might understand:

* My story: This is a simple and direct way to describe an autobiography.

* My life book: This is a bit more concrete and might be easier for a child to grasp.

* The book about me: This emphasizes that the autobiography is about the author, which can be helpful for children.

You could also use pictures and visuals to explain the concept of an autobiography to a child. For example, you could show them a picture of a person and then a picture of a book and say, "This book is about this person's life."

It's important to tailor your explanation to the child's age and understanding level.
