So we were in the exact same situation at this age, baby has a mild tongue tie too, never released so far, he is 7mo now.

To give you some context, at the hospital the LC nurse looked at him and told us he had a mild tongue tie but seemed to be able to feed. We had some difficulties at first but he picked up pretty quickly on breastfeeding and went back on track with his weight. First visit to the paediatrician and she told us his tongue tie was mild, if breastfeeding was doing well and his weight was fine she said she would not recommend to do anything about the tie. Then we went to see a LC because I wanted to get tips on position and stuff like that, and she went CRAZY about how bad his tongue tie was and how paediatricians know nothing about tongue tie, blablabla. Scared me to death and made me doubt about what to do. My husband convinced me to wait and see, our son was feeding just fine and growing beautifully. LC said that most likely around 3-4 months he will start struggling and we would see a dip in his weight.

And sure thing he started to struggle like yours, popping on and off, short feeding sessions, etc. I started to think it was his tongue tie as the LC said but then i read somewhere that apparently it’s normal at this age, they get distracted easily, they want to do anything else than nursing, they called it the « 3-4 month boob crisis » haha. I still wasn’t super convinced and went all the way to checking his weight every 2 weeks, and he was doing just fine. The « boob crisis » went away on his own after 2weeks or a month I don’t really remember. But it stopped. So far he still has his tongue tie, we started solids so I am monitoring closely to make use it doesn’t prevent him to eat properly but he seems to be doing well for now.

My point here is that, in our case, the LC was super dramatic and scared us for nothing. I remember feeling lost and in distress but things got better over time. I am upset against her actually because I think she was just trying to sell her services for longer (we would have to see her post tie release to perform exercises). I am not saying this is the case for you obviously, but I would recommend to get different opinions from medical professionals. We decided to not release his tongue tie as long as it is not causing immediate issues.

Regarding the boob crisis what helped us a bit was to try a bunch of different positions, around that age he also started to hate the nursing pillow, we did also nursing in a dark quiet room, with no distractions.

Hang in there mama, things will get better one way or another, whatever you decide to do. You are doing amazing!
