What developmental milestone comes after an infant can sit unsupported?

• A. Crawl
• B. Stand
• C. Roll over
• D. Walk

Answer: (A)

The typical sequence of gross motor development in infancy moves from sitting to the next stage of autonomous mobility. Once an infant can sit without support, crawling is the next major milestone. Crawling allows the infant to move around the environment on the floor, building essential coordination between the arms, legs, and trunk. This coordination helps strengthen muscles and refine motor planning, laying the groundwork for standing and walking later on. Timing varies, but crawling usually appears around 7 to 10 months, though some babies may skip crawling or use alternative forms of movement. Rolling over tends to occur earlier, and standing or walking generally comes after crawling.
