Tongue tie in my almost 3 year old

Long story, but we just had a wellness check up for my 2 year old (who will be 3 at the end of May) since we just switched pediatricians. Found out, she has tongue tie! I never knew. I never connected the dots from never latching, to being the pickiest eater, to being in speech therapy, and she's been dropping weight percentiles. The new pediatrician just looked in her mouth and said she has it. Our former pediatrician just checked her mouth briefly as a newborn and said "no tongue tie" I remember that. I'm not totally upset it was missed, but I feel guilty that this whole time, all of this was related to her tongue! Next step is to get an appointment with a Pediatric dentist. We haven't taken her to the dentist yet for various reasons, including covid. But we'll be setting up an appointment to check out the severity and such. Her pediatrician guessed it was a grade 2 or 3. I'm just so mind blown 🤯 anybody else have stories like this? I'm not anxious or anything. I'm just curious if other have stories about finding out their kid has tongue tie years later, instead of as a newborn. Ugh I remember beating myself up over not being able to breast feed her because she wouldn't latch. Well, now I know why. Years later. And why she's so far behind in her speech.
