At what age do infants typically lift their head when on their belly?

• A. 1 month
• B. 2 months
• C. 3 months
• D. 4 months

Answer: (B)

Infants typically begin to lift their head while lying on their belly around two months of age. This milestone is crucial as it indicates the development of neck and upper body strength. At this stage, babies are gaining better control of their head and can lift it to about a 45-degree angle, which is essential for later milestones such as rolling over and sitting up. This movement reflects the engagement of the neck muscles and the coordination of their physical capabilities, which continue to develop rapidly in these early months.

While younger infants may show some head movement when lying prone, the ability to lift the head effectively and maintain that position generally occurs around the two-month mark, marking an important step in their motor development.
