What response occurs when a baby's cheek is stroked?

Moves arms and legs
Starts sucking
Moves head towards the finger
Grips stronger

The correct answer is: Moves head towards the finger

When a baby's cheek is stroked, the natural reflex that occurs is for the baby to turn their head toward the source of the stimulus, which is typically referred to as the rooting reflex. This reflex is an adaptive behavior that enables the infant to find the breast or bottle for feeding. The movement of the head towards the finger or object they feel on their cheek helps them locate and latch onto a food source, demonstrating their instinctual response to touch. This response is essential for survival and is a foundational aspect of early development, promoting feeding and bonding between the infant and caregiver. The other options—such as moving arms and legs, starting to suck, or gripping stronger—are responses associated with different stimuli or reflexes, but the specific response to a stroke on the cheek is the subtle but significant head movement.
