Query: Leapfrog Touch and Tug Discovery Book

I purchased this book for my 6 year old disable grandson as he loves this toy. The problem is sometimes it goes on and sometimes it doesn't. I would have returned this book but it would has cost too much to return it.This is not this first book that I have had, this is our 4th and this one was the worse.Anyway it makes him Happy and that's what's important.Diana
