Query: Don't know why, but they love it

My boys love this book. We got it when they were about 12 months, and at 18 months it is still a favorite that they pull from the book stack every day. It's solidly built and has stood up to twin boys grabbing and chewing on it for 6 months with no signs of wear. They love it when we ask them questions about each page -- "where is the ball", etc. They point at each picture and identify the items. They are not necessarily all of the first 100 words I would pick, but the boys enjoy it and have learned all of the words.
