Query: I bought an extra for the part-time care giver!

This book was given to us by our pediatrician and thank goodness. I have found the month to month guide very helpful in anticipating phases in our child's development. I am purchasing an additional book for my mother-in-law who also cares for my son on occasion. There is so much new information on child's health since our parents were starting their families and this book is concise and clear enough for any reader to quickly find what their looking for. From general health to feeding schedules to developmental milestones this book covers it all!
