My DS is 4 months old and is not a really great nurser. He constantly slips off the breast, clicks, and has problems everting his upper lip. He is still gaining well, though, because as a tandem nursing mama, I have an enormous milk supply that basically pours into his mouth if he's anywhere in the vacinity.
I have had a few incidences of nipple pain and I had a little blister on one side a few weeks ago, but it's generally not painful to nurse him.
My friend who is a PA looked at his mouth and he definitely has a thick, tight, low upper lip frenulum. She gave me the name and number of a pediatric dentist who clipped the lip tie of her oldest daughter, who is now 4 years old. This dentist won't do the procedure, though, until the child is at least 2 years old.
So would you pursue getting it clipped now or not? I have heard that the upper lip procedure is more invasive and complicated than clipping a tongue tie.
