I found  this book online and ordered it from the publisher. I really like the exercises, they're so easy and you can do them anywhere - it's not like you need any props or anything, and they're really fun! My husband loves the book too - he likes physical things and this book has been encouraging him and the kids to play. It's easy to read. i would've like to have seen some photos (the exercises are illustrated with drawings) but it's otherwise really great, and it explains how all the exercises help the kids develop. I think it's a 9/10, and at $29.99 it's pretty good value for money. I think we'll get a lot of use out of it.
