The incredible developmental changes and regression periods that all babies go through during the first 20 months of their lives. Age-related fluctuations and the need for body contact and attention are all related to major and quite dramatic changes in the brains of children. These changes enable a baby to enter a whole new perceptual world and, as a consequence, to learn many new skills. The first 20 months after birth when all babies take ten major development leaps. Learn how to encourage each leap forward. Help for your baby's times of fussy behavior: Cranky, Clingy and Crying. Recognize the on-set of stressful times and join your children in coping with them. All normal, healthy babies appear to be more fussy at very nearly the same ages, regression periods, and sleep less in these phases. This book will help your baby, and you, get the most out of these developmental phases.
