My 7 month old loves this book! When I show it to him he smiles andsqueals with delight. As most of of know, 7 month olds not only delight in the words and the pictures, but they like to feel and taste the story as well! This book is not holding up. The "lift flaps" are very thin and seem like they are going to tear off of when my baby lifts them. I guess I'm just used to his other favorite book, "What Does Baby Do" another lift the flap book by Begin Smart. That (like all of their books) is VERY durable! I suppose we'll just have to be very gentle with "Where Is Baby's Belly Button?" It is a great book, however I wish it was more durable so it could last for our next child!
