Every day in many countries, new parents are encouraged to "train" their child to sleep - a practice in which they ignore their baby's crying and distress. In this groundbreaking book, the authors present important research into babies' emotional and brain development, and offer gentle sleep techniques that take into account babies' natural sleep habits. They show parents ways to tune into how their baby thinks and feels, so they can be more responsive to their child's needs. Babies thrive when their parents are sensitive to their needs, both during the day and t night. We believe this type of parenting also helps build a powerful bond between baby and parent - a connection that lays the foundation for the child's healthy emotional and psychological development.
