Late fixing tongue tie

Sarah

My little one is 7 weeks old. I've been having issues this whole time, and just today I finally met with a lactation consultant. It turns out that my baby has a tongue tie and a slight upper lip tie. She only ate one ounce during the weighed feed of both breasts, which explains why she eats every 45 min to an hour all day. Has anyone had a tongue tie fixed so late? We have thrush so the earliest she can get it fixed is 9 weeks old.
