Query: My baby's favorite!

I am soon going to need to purchase another copy of this book. My daughter loved this book from the time she was nine months old because of the "surprise" value of having a matching colored animal pop out of the page for each color. It's fun to read the colors, and then slide out the hidden animal and read the animal name. It also encourages the baby to say the animal name with you--one of her early words was after I said "green" and she whispered "fro(g)". Now that she is 13 months old, it is still her favorite book, but now she slides the pages for herself. The book is sturdy, but I will still probabaly have to buy another copy with this intense use. I am also ordering other books in the series.
