There are a wide range of behaviors that can be considered “normal” in terms of reaching certain developmental milestones. Knowing what to expect from babies, toddlers, and preschoolers can help families know what to look for and what to do to help their children. “Early learning guidelines can be a valuable part of a comprehensive high quality system of services for young children, contributing to young children’s educational experiences and to their future success.” (NAECS/SDE, November 2002). These resources may help families better understand their children’s development.
