Infants often fall head first because ___________.

• A. they usually fall backward when moving, not forward
• B. they are prone to syncopal episodes
• C. their blood pressure falls sharply upon standing
• D. their head is large and heavy in proportion to their body

Answer: (D)

Infants often fall head first primarily due to the proportionally larger and heavier head compared to the rest of their body. At this stage of development, their neck muscles are not yet strong enough to stabilize their head effectively, making them top-heavy. This anatomical characteristic significantly contributes to their tendency to tip over forward when they lose balance, leading to head-first falls. The combination of a large head and underdeveloped neck strength means that when an infant is in a standing or sitting position and their center of gravity shifts, they are more likely to fall forward rather than backward or sideways. This understanding is crucial for caregivers to ensure safety measures are in place as infants learn to sit, crawl, and eventually walk.
