Well ENT says no tongue tie but had never even heard of a posterior tongue tie so that doesn't seem very convincing! And they don't separate upper lip ties at all so no go there anyhow. Grrrr. Very, very frustrating. Have a name of a doc in the area that does tongue ties so am going to call them tomorrow to see if they know anything about posterior tongue ties and if they clip upper ties. If not, I think I will let it go. I'm not even convinced he has a tongue tie and the upper tie may or may not be a problem. For my sanity I can't stay obsessed about this, you know? I'm pumping to supplement and he is starting to grab at my food so maybe solids are close and I can feed him lots of avocado!
Both DS and DD have upper lip ties. I have not had latch issues with either one. DS's resulted in a gap between his front teeth. DD just starting teething on top so we will see. I asked both our pediatrician and pediatric dentist about them, and neither was really worried. The dentist said that DS's will need to be cut before his adult teeth come in to help with alignment, but otherwise it is not a problem.
BTW, both my mom and I had the same problem. We both had our lips corrected when we got braces.
