9 Newborn Reflexes
Learn about primitive reflexes, including why and when your baby will root, grasp, startle, thrust her tongue, and more
What It Is: Moro (or startle) reflex
Check It Out: Sit your baby upright for a few seconds with your hands lightly gripping her underarms, and your fingers supporting her neck then suddenly but gently lower her back a bit. She’ll throw out her arms and legs and extend her neck, as if to say, Pick me up! Loud, unexpected noises may elicit this reflex, and she may even cry when especially startled.
When It Disappears: Around two months.
