Tongue tied

Ao recently my baby boy has been super fussy. Refusing to eat always screaming never sleeping and so we made a few trips to the drs. About a month ago i was told he had lost to much weight and i needed to also add formula to his diet.( i was exclusively breastfeeding) when i was told that i about lost it. I still feel horriable about it. Anyways we were also told he has reflux,teetheing,and thrush. we had started doing the formula twice a day and hes starting to pack on the pounds now. But he is still refusing to latch for feedings. We were doing great too. So this past visit the dr said hes tongue tied and it makes it very difficult to nurse so we are having the minor procedure done to correct this plus later on in life his speech wont be affected and so on.

Has anyone else had to do this??
