Sucking Reflex


video by Janelle Aby, MD

In this clip, the infant shows how easily the sucking reflex can be elicited. As soon as the baby feels his thumb at his lips, he begins sucking. Sucking is a self-soothing manuever for infants; an examiner can take advantage of this reflex (and its ability to soothe a fussy baby) by allowing the infant to suck on a finger or pacifier during the examination.
