At 7 months, the infant begins to crawl, using arms and dragging the trunk and legs. Which option best describes this milestone?

• A. Crawling, using arms and dragging trunk and legs.
• B. Creeping.
• C. Cruising.
• D. Walking.

Answer: (A)

Infant gross motor development includes distinct crawling patterns that reflect how mobility emerges. At about seven months, a common form of crawling is the army crawl, where the infant propels forward using the arms while the trunk and legs stay on the floor. This matches the description of crawling with the trunk and legs dragged along. It differs from creeping, which typically involves the belly lifted off the floor and movement on hands and knees. Cruising involves pulling to stand and moving along furniture, and walking is upright ambulation without support, usually around the first birthday. So the best description for this 7-month milestone is crawling with the trunk and legs dragged along, i.e., army crawl.
