Being one(twelve to twenty-four months old) is a time of explosive growth for babies. Their brains are growing from one-quarters of adult size by two years of age. They are ready to achieve exciting milestones in language and emotional development, and new skills abound as they learn to walk, share ( though not much), and comminicate with loved ones. This year offers a thrilling challenge for babies and parents alike.Throughout this book, Maureen O'Brian, Ph.D., an expert in child development and former director of the Brazelton Touchpoints Center at Boston's Children's Hospital, describes this remarkable journey in rich detail.
