Reviews
My baby loves the mobiles and stimulating images that I made for him from the book-- Made with paper plates, copy paper, black and red pens, they're simple, inexpensive, and effective. There are a couple exercises out of the dozens in the book that refer to stimulating baby's sense of smell with perfume-- But that shouldn't condemn the book as a whole. Any parent who objects to subjecting his/her baby to perfume doesn't need to do the exercise. There are other smell games that involve smelling an orange, various spices, your dinner-- Clearly less ostensibly harmful than smelling perfume. The activities are "mix and match" so you don't have to have your baby smell perfume.
The book is so inexpensive, yet filled with good information. It doesn't matter that the book is old-- The information in it is really timeless. This can't be compared to the "Baby Plus" system, which from what I've read, doesn't really factor in the value of a parent spending quality, interactive time with her child. This book is about helping your baby experience the world, not snap more synapses.
If you want to learn about how you can spend more quality time with your baby and help him learn new things by experiencing things around him, get this book. Just because the book was written in the 1980s doesn't mean the information is outdated. Are the laws of gravity outdated? I did give it 4, not 5 stars because some of the information on resources/ purchasing toys is outdated (the oft-mentioned "Cookie Monster Crawl-Along" infant skateboard does not exist), but this is a minor flaw compared to the other values stored up in this book.
