Great Book about Development

A friend of mine in my moms group recommended this great book about the emotional development of your child. I purchased it this week and just received it. I opened it and cannot put it down. It is written by a pediatrician and, after reading as few as 10 pages, I feel less concerned about Brett and her 'personality.' I maybe shouldn't make a recommendation before reading the entire book, but it is a book that you may pick up and put down during different ages and stages of your babies life. Check it out!
