Query: Good book!

My 13 month old son loves Blue's Clues and this was his first BC book. He loves "discovering" Blue's friends hiding behind the flaps. However the sandcastle flap did not last longer than 3 days ( that's why I only give 4 stars for the book). It was also very scratchy and not very good for Baby's that like to chew on almost everything.If the sandcastle was constructed a tad bit different this book would be wonderful.
