These are the developmental milestone steps in order, beginning with the one which happens first and ending with the one which happens last: holding head up, rolling over both ways, rising up on hands, crawling, sitting without support, standing with support, and walking.
Developmental milestones are a set of functional skills or age-specific tasks that most children can do at a certain age range. Skills such as taking a first step, smiling for the first time, and waving bye are called developmental milestones. Children reach milestones in how they play, learn, speak, act, and move.
Recognizing when a child has missed a developmental milestone allows the parent to seek additional information, screening, evaluation, and if necessary, treatment for her child. Most developmental delays in children are not serious, and children eventually catch up with their peers.
