Breast crawl
Breast crawl is the instinct of mammal newborns to move towards the nipple and attach to it for breastfeeding all by themselves. In humans, if the newborn baby is put on the mother's abdomen, the movements start 12 to 44 minutes after birth, followed by spontaneous suckling at 27 to 71 minutes after birth.
The infants use their sense of smell in finding the nipple. The areola smells similar to amniotic fluid, the baby recognizes this smell on its hands and begins to move towards the breast. As shown in a 1994 study in which one of the breasts was washed with unscented soap and the baby preferred the other one. They also use visual stimuli and auditory.
