Which posture is explicitly listed as an infancy developmental posture (0-11 months) in the material?

• A. Prone
• B. Sidelying
• C. Standing in a walker
• D. Kneeling

Answer: (A)

Prone is the infant-friendly posture at this stage. Lying on the stomach is explicitly listed for infancy (0–11 months) because it is the foundational position that drives early motor development: it helps the baby lift the head, begin to extend the neck and spine, and develop weight-bearing through the arms. This stance sets up the trunk and upper-body strength needed for rolling, pushing up, and eventually sitting and crawling. The other postures—sidelying, standing in a walker, and kneeling—are not the infancy posture specified in the material; they’re associated with later development or specific therapeutic positions, not the 0–11 month developmental listing.
