sucking blisters

sucking blisters

the pale soft pads on the upper and lower lips of a baby that look like blisters but are not. They form as soon as the baby begins to suck well at the breast or on a bottle. They seem to augment the seal of the lips around the nipple or breast. Some babies, who have sucked on their own fingers, hands, or arms before birth, are born with them.
