What reflex does an infant display when turning its head toward an object that touches its cheek?

The rooting reflex is a natural instinct that infants possess, which is essential for breastfeeding and early feeding practices. When an object, such as a finger or a nipple, touches an infant's cheek, the infant instinctively turns its head toward the stimulus and opens its mouth. This reflex action helps the infant locate and latch onto the breast for nourishment.

The rooting reflex typically emerges shortly after birth and is often assessed as part of a newborn's physical examination. It typically lasts until the infant is around 4 months old, as other feeding skills and behaviors develop. This reflex plays a crucial role in early development by promoting feeding and bonding between the infant and caregiver.

The other reflexes listed, such as the grasping reflex, walking reflex, and swimming reflex, serve different purposes and are triggered by different stimuli, but they do not involve the head turning in response to a touch on the cheek. The grasping reflex, for instance, is activated when an object is placed in an infant's palm, while the walking reflex is related to stepping movements when held upright. The swimming reflex occurs when an infant is placed in water and instinctively moves its limbs to paddle. None of these reflexes correspond to the action observed with the rooting reflex, thereby
