DS is my first baby and is now almost 8 weeks old. I have had pain and nipple trauma when breastfeeding him from the beginning and am now mostly pumping despite seeing a woman who is an IBCLC and cranial-sacral therapist for over a month now. I asked her about posterior tie a couple weeks ago and she said she believes it is way over diagnosed and likes to see how they do with the CST before pursuing that diagnosis. Well she hasnt brought it up again but my midwife gave me the number of a dentist in my state who specializes in this area (hard to find, I know!) and I have emailed him these photos, waiting to hear back.
Other than my pain and trauma, he clicks almost constantly when attempting to suck, otherwise he is just downright chewing. Even before I started pumping he was getting enough milk and growing, but I think it is because I have been blessed with a good supply. He usually nurses for very short periods and does not stay on to suck after the initial let down. He also clicks a lot on the bottle.
I am really hopeful that this looks like a posterior tie, because otherwise I think I am at the end of my options and will have to continue to pump long term :( Also I just noticed a thick frenulum to his upper lip (bottom photo), not sure if this is normal but his upper lip is always tight and his lower lip is always sucked in when he latches.
