The Rooting Reflex


3 months

From The Biology of Prenatal Development.Buy Now

Script: In contrast to the withdrawal response seen earlier, stimulation near the mouth now evokes a turning toward the stimulus and an opening of the mouth. This response is called the "rooting reflex" and it persists after birth, helping the newborn find his or her mother's nipple during breastfeeding.

All ages referenced to fertilization, not last menstrual period. One month = 4 weeks.
