The rooting reflex is a natural instinct seen in newborns. When a baby's cheek is stroked or touched, they turn their head toward the stimulus and open their mouth. This reflex helps infants find the breast or bottle for feeding, ensuring they receive the nutrition they need for growth and development. This reflex typically appears at birth and usually fades by around four months of age. It is part of a group of reflexes that are crucial for survival in early life. The rooting reflex is an important aspect of infant behavior and is often assessed by pediatricians during routine check-ups.
