Motor skills in infancy emerge in a predictable sequence, but the timing may vary from one infant to another. For example, most babies will develop control of their neck muscles before they can sit up unsupported, but some babies may achieve this milestone earlier or later than others. Similarly, most babies will learn to crawl before they learn to walk, but the age at which they achieve these skills may vary.
