Easy to use!
Format: Hardcover, Format: Hardcover
We had a Spider-Man one for my son and he loved it so we got these princess ones for my daughter and she loves them. They’re nice because it tells you when to turn the page and push the next button to read the story so she can “read” to herself now.
