I ordered this book since my son was starting soccer. I thought it would be a good way to get the message across. He very much enjoyed the book. When he was frustrated at a game or practice, we would recall the book and he'd calm down. Excellent tool.
I was not really expecting much for the price. The small paperback book doesn't have but a few pages in it giving short examples of the subject matter, one example per 2 pages allowing only a few examples per book. For a buck a book, it is okay for using a base communication with your children as a referral guide to identify with daily challenges of the particular topic. I do think it is overpriced for the amount of information, but it can create story-time into learning-time.
