Some of the factors that have been demonstrated to support healthy development in children include responding to children in a predictable way, showing warmth and sensitivity, and having routines and rules. Sharing books and talking with children, promoting movement and exercise, and following effective nutrition and feeding practices also contribute in important ways. Being aware of developmental milestones, which give a general idea of the changes to expect as a child gets older, is also useful, although it is important to remember that all children develop at their own pace.
