Discover why your preschoolers do the things they do. This lesson will help you to understand Ages and Stages from birth to five years; remember what life is like for young children; understand the child's perspectives and needs; learn how to help our children learn and grow in healthy ways. The information is considered typical for this age. If you have questions about your child's development, contact your pediatrician or health care professional. If we do all we can do to help children develop and grow now, they will have the best chance to succeed in life.
