Suckling is a wonder of natural engineering that has helped sustain the human race for millennia. But exactly what happens when your baby suckles at a mother's breast?
Once the nipple is correctly positioned, feeding occurs by a process of peristalsis. That is the wave-like motion seen elsewhere in the body during digestion. The tongue, jaw, lips and palate are all part of the process.
Here is the process in detail:
The baby draws your nipple and much of the breast tissue lying behind your areola into his/her mouth.
Palate = Roof of the mouth
Peristalsis = Wave like motion caused by muscle contractions.
Rooting = The reflex in newborn babies that prompts them to turn their faces towards their mother’s breast and make sucking motions.
