• A. 4 months
• B. 5 months
• C. 6 months
• D. 7 months

Answer: (C)

Infants typically lift their chest and head while bearing weight on their stomach around 6 months of age. At this stage of development, infants gain significant strength in their neck, shoulders, and back muscles, allowing them to push up with their arms when lying on their stomach. This milestone is crucial as it helps in developing upper body strength and plays an important role in further motor skills, including rolling over, crawling, and eventually sitting up. Lifting their chest and head also allows infants to explore their surroundings more effectively, fostering cognitive and sensory development through improved visual engagement with their environment.

Achieving this milestone at around 6 months indicates that the child is developing appropriately in their motor skills, reflecting both physical growth and neurological maturation.
