How a Lip-Tie can affect breast-feeding

A normal breastfeeding motion is accomplished when the infant is able to flange their upper lip outward toward their nose, allowing the mucous membrane portion of the lip to contact the breast. When the upper lips inner mucosa or frenum is attached to the alveolar ridge (as seen below) and the lip is unable to fully move upward, it can create a shallow latch. This can allow for the passage of excess air to be introduced into the infants belly and thus result in reflux.
