In infants, physical development moves from which area?

The feet up
The head down
The spine out
The hands up

The correct answer is: The head down

The correct answer reflects the principle of cephalocaudal development, which is a key concept in understanding the growth patterns of infants. This principle suggests that physical development in infants progresses from the head downwards. Infants exhibit control over their head and neck muscles before they develop control over their trunk and legs. For instance, they can lift their heads while lying on their stomach long before they can sit up or crawl. This sequential order is essential for their functional mobility and overall coordination. The other choices, while they suggest different patterns of growth, do not accurately represent the established developmental norm in infants. Thus, understanding that physical development in infants typically starts at the head and moves towards the feet is crucial for recognizing developmental milestones during early childhood.
