BUY THIS BOOK if you are expecting or give it to someone who is! This book is designed to give your baby every opportunity to develop as they should. I use the excercises with infants in therapy who have eye turns (strabismus) or amblyopia (lazy eye), and I've modified some for older kids who skipped steps developmentally and are now delayed in school and/or physical activities. I couldn't believe my mom had a copy when I was a baby. I learned about this book in graduate school, and I've been in love with it ever since...though they could change some of the pictures--most of us have diapers on babies all the time now!
