I always thought baby's lips are to be flanged out when breastfeeding. This is a problem we have with getting a good latch. I was just reading about tongue tie and in an LLL article it talks about fish lips as if it's a bad thing. The article is
It's the 7th paragraph:
"During breastfeeding, the infant’s lips should maintain a seal around the breast, but should not move much. If the lips are turned outward like “fish lips,” the baby may be using them to move milk from the breast instead of the tongue. "
So are fish lips and lips flanged out different?
