Best baby book I have read yet. We got this from our pediatrician. I started reading it right away. It has great detail on ages 0 – 6 months, then strangely lumps months 6-12 together. Would have liked the same detail in those months as the first 6. The last third of the book is all the depressing diseases and illnesses that babies get. Good book to keep as a resource if any of those things should happen. *knocks on wood*.
