This book was given to me by a friend at my baby shower, and from the cover, I had thought it was going to be more things like, "Make your kids believe in Santa Clause until they're 30."
This book should be more accurately named, "Exercises with Babies." Though each experiment is set up like a true experiment, each one is more of an activity that you can do with you spawn (ranging ages from 0-24 months) to better understand their developing mind and body. They are in no way meant to test their proficiency or development level, and actively steer away from anything that would make you question whether or not you child is performing at the same speed as "normal" children.
It has a suggested age range for each experiment, a level of difficulty, and what type of exercise it touches on (motor or social skills, etc).
Each one also has a description of how to perform the experiment, a description of what the results would be, a section describing the actual scientific research and findings behind your dumbed down version, and a "Take Away" section that basically sums up what this all means to you and your little one.
I really liked this book as it was easy to read while pumping at work, interesting to learn about certain reflexes and methods as to how my daughter is growing and learning, and other insights about general development in humans.
For example, in the book they mention a "fencing reflex" in which an infant laying on their back will extend one arm out in front of them, and hold the other up as if in a fencing stance. With my daughter, we also noticed that she will kick whichever leg is "in front of her." Hour of head turning, leg kicking entertainment followed.
It's a good book for anyone interested in human development, or anyone who wants to try some exercises on their (or other peoples) children.
