Introduction[edit | edit source]The rooting reflex is an innate response of the head due to the stimulation of the face, mouth, or cheek by touching/stroking (the head is turned towards the side of the stimulus).[1] It is a brainstem mediated primitive motor reflex also called the frontal release reflex.

This reflex has also been observed in the apes and other mammals.[1] The presence of the Rooting reflex has also been linked to altriciality-meaning that the newborns are unable to feed themselves (unable to source for food) with the help of locomotion. Therefore in response, the caregiver feeds the young one taking the reflex as a cue.[2] Stimulus[edit | edit source]The reflex commences when the corner of an infant’s mouth is stimulated by touching/stroking. [3] Response[edit | edit source]The newborn will turn their head towards the stimulus(finger or nipple) and open the mouth wide with tongue thrusting (tongue sits too forward in the mouth).[3] Duration[edit | edit source]The rooting reflex is present at birth (around 28 weeks of gestation) and disintegrates about 4 to 6 months (until the frontal lobe of the cerebral cortex matures.)[3] [4] The healthcare provider strokes the corner of the mouth of the baby and the infant turns their head towards the stimulated side. For eg., if the right side of the corner of the mouth is stimulated then the baby turns its head to the right side. Difference between Sucking and Rooting Reflex[edit | edit source]

Babies are born with newborn reflexes. These are involuntary movements that are a normal part of infant development. For example, if you put your finger in your newborn's hand, the baby will take hold of it. How Is My Baby Moving?Newborn reflexes show up soon after birth. They include:
These early reflexes gradually disappear as babies mature, usually by the time they are 3–6 months old. How Can I Encourage My Baby?Give your baby space to stretch and move the arms and legs. Let your baby get some tummy time when awake and alert to help strengthen back and neck muscles. Always stay with your baby during tummy time. As your baby grows, these reflexes will become less noticeable and more purposeful movements will develop. When Should I Call the Doctor?The doctor will check newborn reflexes as part of your baby's routine checkups, making sure they're the same on both sides, and taking note of when they disappear. Be sure to tell your doctor if you have any questions or concerns about your baby's movements. /content/kidshealth/misc/medicalcodes/parents/articles/movenewborn |
