Which age range is associated with typical crawling development?

• A. 9 months.
• B. 3 months.
• C. 12 months.
• D. 15 months.

Answer: (A)

Crawling onset is the motor milestone where infants coordinate moving on their hands and knees, which builds the strength and coordination needed for later walking. This typically appears around nine months, with a common range roughly from seven to ten months. At nine months, most babies have enough trunk control, hip stability, and arm-leg coordination to lift the chest off the floor and move in a hands-and-knees pattern, sometimes starting with belly-crawl or other variations before true crawling. Seeing crawling start as early as three months would be unusually early for this skill, since infants at that age are still developing head control and rolling. By twelve months, many children are transitioning toward standing or walking, so crawling is often already established or transitioning out. Fifteen months is later than the typical window for crawling, though individual variation exists and some children may still be crawling while others have moved on to walking.
