Book excerpt: A three-year-old is a real puzzle to parents, sometimes anxious to please and befriend, sometimes strong-willed and difficult to get along with. At the heart of the three-year-old’s personality is often an emotional insecurity—and this causes a host of problems for parents! Drs. Ames and Ilg, recognized authorities on child behavior and development, help parents understand what’s going on inside that three-year-old head, what problems children have, and how to cope with the toddler who is sometimes friend, sometimes enemy. Included in this book: • Jealousy of a new sibling • Toilet training • How to improve a child’s eating habits • Friendships with peers • Common fears • Developing language skills • Nursery school • Books for parents and three-year-olds “Louise Bates Ames and her colleagues synthesize a lifetime of observation of children, consultation, and discussion with parents. These books will help parents to better understand their children and will guide them through the fascinating and sometimes trying experiences of modern parenthood.”—Donald J.
