I received this book for free from my OB doctor when I got pregnant with my second child. I read about half of it, and I don't think I'll finish it. It's very repetitive and unorganized and doesn't explain things well. One thing it talks about is creeping, crawling, and cruising. I never could figure out from this book what those terms specifically meant. But the book kept going back to those terms. The book said that "cruising is not walking"... well then what is cruising? I had to look up the definition somewhere else to finally understand. That was true with a lot of other things mentioned in this book. Some of the activities they say you should do they don't describe well enough, so I couldn't figure out what they were saying to do. The pictures helped most of the time, but other times, the pictures didn't seem to match what they were describing.
And I definitely agree with another reviewer that said some of the activities are not appropriate, like a 2-6 month old rolling down an incline or a 6-12 month old climbing a ladder?!?! Yikes. No thank you. I think I'll look for another book.
