A must book for children
Format: Paperback
I got this book 15 years ago at a garage sale and it was one of my kids favorite books of all time. We took it with us everywhere we went (in the car, on vacation etc). My daughter is now in her 20's and she works at a daycare center. She wanted to get some books for their library and when I reminded her of this book she had to get it for them. It has quickly become the classroom favorite, the children ask for her to read it to them daily.
