DS was 6 wks when we had his frenectomy with an ENT. I consulted a pediatric dentist re the lip tie, but he didn't seem to think it was severe enough to warrant anesthesia to do the procedure, but we decided that if he has to have any dental work in the future requiring it, we'll do it then because I can already see it's going to cause a huge gap in between his front teeth.
His palate has widened slightly, but not too much. I've been told the longer I breastfeed the more it will come down on it's own, but my goal is only 18 months, since my patience for the discomfort I'm exeriencing while nursing is running low. I just can't take it much longer! It's torture at times! He is still on the end, nursing on the nipple only,and totally refusing to take much, if any, areola into his mouth. <sigh> I am currently looking into cranio sacral therapy as an alternative.
Coincidently, I was TT (my mom gave up BFing early on) and had/have a high arched, narrow palate. I had to have a palatal expander when I had braces (also had the big gap) as a teenager, so I imagine that'll probably be the case for him too. He's so much alike me, it's scary!
