Sabrina Freidenfelds MPH, IBCLC is the director of Then Comes Baby and one of our bottle-feeding experts. Freidenfelds recommends that parents learn to recognize the difference between genuine feeding and the suck reflex, since babies can draw so easily from a bottle nipple. Volume alone won’t tell the tale, and neither can the baby. “Babies can’t regulate,” she explains. “They have a suck reflex and a swallow reflex, so if it’s there and flowing in their mouth, they can chug down a bottle way beyond their needs.”
