Testing Your Newborns Reflexes

Newborn reflexes in the first moments and even months of life form the building blocks of future development. Movement that starts out as a reflex soon turns into purposeful, cognitive and physical activity. Your health care provider will test your newborn for these reflexes soon after birth and again at your first check-ups. You can test these reflexes yourself as well.

Grasp Reflex Testing Your Newborns Reflexes

If you place your finger or other slim objects in your baby’s palm, his fingers will grasp the object tightly—this is more specifically known as the palmar reflex. This reflex is also present in the feet causing the toes to curl, known as the plantar reflex.. It can be tested by lightly touching your baby’s feet or toes. The palmar reflex only lasts until your child is about 6 months old. The plantar reflex can last until 9-12 months.

The reflex is elicited while a child is lying on his back by turning the head to one side, say right. The reflex occurs whereby the right side limbs will extend straight, and the left side limbs will flex. And vice versa when the head is turned to the left side. This reflex can be present up to about 6 months of age or about the time your baby begins rolling over (back-to-stomach) competently and regularly.
