What response occurs when an object touches or strokes the infant's cheek?

When an object touches or strokes an infant's cheek, the response is known as the rooting reflex. This is a natural reflex that infants are born with, which helps them locate the nipple for feeding. When the infant's cheek is stroked, it instinctively turns its head toward the stimulus and opens its mouth. This reflex is crucial for breastfeeding, as it helps the baby find the breast or bottle more easily.

The rooting reflex typically disappears by 4 to 6 months of age as the infant develops more voluntary control over their movements. Understanding this reflex is fundamental for caregivers and healthcare providers, as it demonstrates an infant's readiness to feed and may indicate proper neurological development.
