Your Baby's Reflexes

Instincts are powerful. Your baby is born with instinctive reflexes that assist in survival.

Here's a quick review of a few of your baby's reflexes, to help you marvel at your newborn.

• Moro or “startle” reflex: This occurs when your baby's head shifts position quickly. Or when her head falls backward. Or when your baby is startled by something loud. She will react by throwing out her arms and legs and extending her neck. Your baby will then quickly bring her arms together. She may cry when doing this. This reflex should go away after two months.
• Rooting reflex: This is how your baby hunts for her mother's breast. If you gently stroke the side of her cheek with your finger, she will turn her head toward your finger. This lasts for three to four months.
• Grasp reflex: Your baby will clench her fist around anything pressed into the palm of her hand. You can show this to a big brother or sister. Say, “The baby wants to hold on to your finger.” This reflex goes away at five to six months.
• Stepping reflex: If you hold a newborn baby upright under her arms with her feet on a hard surface, her feet will make a stepping action. This happens even though it is a long time before she is ready to stand or walk. This usually lasts a couple of months.

Ask your pediatrician if you have any questions about your baby's reflexes.
