This document outlines motor development milestones from birth to 6 years of age. It provides descriptions of physical skills infants and toddlers should meet at various ages, such as raising the head, grasping objects, sitting up, crawling, walking, running and jumping. It also lists visual and auditory milestones. For each age range, it identifies signs that could indicate developmental delays and recommends consulting a pediatrician if any of these signs are present. The milestones provide parents with a general guide to monitor children's progress but also emphasize each child develops at their own pace.
