How come babies can breathe underwater?

Your baby, however, is born with a reflex called the laryngeal reflex, or gag reflex. The larynx (the soft tissue at the back of your baby's throat) closes when they go underwater to block their airway. It kicks into action when they feel the water on their face, nose or throat. Infants up to 6 months of age will hold their breath naturally when their heads are submerged in water. Their heart rates slow at the same time, conserving oxygen, and blood circulates most between their brain and heart.
