I checked out this book from the library because I realized that I didn't know if Baby was hitting the milestones that are typical of babies. Especially because she wasn't walking at 13 months. Which is fine and normal! But a mom starts to wonder about it a lot when all the other (younger) babies at library storytime are literally running circles around Baby.
The book is broken down in sections, covering newborn to age 3. I jumped in at the 9-12 month section, and also read the 12-18 month, 18-24 month, 2-2 1/2 years, and 2 1/2-3 years sections (to know what I have to look forward to). I liked the section breakdowns, and how each part had 'major milestones', 'summary of development', and then went into further details covering growth and health, sleeping, motor development, learning, communication, coordination, etc. It was a lot faster to read than my What to Expect the Second Year! The book was a bit repetitive because I would read all the sections in one go, afraid to miss anything, but I could have really skipped reading the summaries (use them for quick reference).
The book covered delays and disorders, but was never scary. Overall it was a reassuring book. I'd recommend it to other parents.
