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)

In infancy, postural development centers on positions that promote control of the head, trunk, and overall body organization. Lying on the stomach (prone) is a foundational posture for babies aged 0–11 months because it encourages lifting the head, stabilizing the upper body, and extending the spine. This position builds the neck and upper back strength needed for rolling, pushing up on the arms, and eventually crawling and sitting independently. When the material lists an infancy developmental posture for this age range, prone is the one that fits best because it directly supports these early motor skills and their progression. The other postures are not the primary infancy-listed postures for this age range. Sidelying is more of a transitional or alternative resting position that appears later in development or in therapy contexts. Standing in a walker and kneeling require greater trunk, leg, and balance control and are typically seen after infancy, or with assistive devices, rather than as standard infancy postures.
