The sucking reflex is a natural instinct seen in infants, allowing them to feed effectively. This reflex helps babies latch onto their mother's breast or a bottle, ensuring they receive the necessary nutrients for growth and development. It typically begins in the womb and is fully developed at birth. This reflex is not only crucial for feeding but also provides comfort to babies. When they suck, it can soothe them and help them feel secure. The sucking reflex usually diminishes as children grow older and transition to solid foods, typically around six months of age.
