what reflex helps the baby knows how to ear
Moro reflex. The Moro reflex is often called a startle reflex because it usually occurs when a baby is startled by a loud sound or movement. In response to the sound, the baby throws back his or her head, extends out the arms and legs, cries, then pulls the arms and legs back in. A baby's own cry can startle him or her and trigger this reflex. This reflex lasts about 5 to 6 months. Tonic neck reflex. When a baby's head is turned to one side, the arm on that side stretches out and the opposite arm bends up at the elbow.
