I want to stress that I don't diagnose tongue-tie based on what it looks like. Well, I do, but the most important criteria for diagnosing tongue-tie is the description the mother gives:
better with a shield
reflux, food/stomach sensitivity
poor weight gain
It is still common for your health care professionals to not recognize anterior or posterior tongue-tie. It is up to YOU to take responsibility. In most cases your pediatrician is not going to take the lead with this. If everything else your Leader or LC has suggested has not helped your situation, consider tongue-tie. It is not always an easy diagnosis. Learn about tongue-tie and pursue treatment if you still feel, it may be what is going on. The sooner you get treatment and prevent further deterioration of breastfeeding (bad suck habits, low milk), the better off you will be able to provide breastmilk to your baby. Will babies out grow it? Some will. Only if the symptoms are mild...maybe will babyout grow it.
Posterior tongue-tie is easily treated in the office within minutes.
Most of the time no further treatment in the office is necessary.

"When I went to see Dr. Punger, I was really not thinking tongue tie, but reflux for my 6 week old baby. I was very sore from the baby clamping down so hard on me. She had to suck very hard to compensate for the difficulty in swallowing that the very subtle posterior tongue tie caused. This caused gulping, gas, reflux, and her never seeming to get enough though I could see the milk dripping from me. Her strong, tense suck also created over active let down and foremilk/hindmilk imbalance=green, explosive diapers. Since the tongue clipping, baby is nursing so much better, finally gaining weight, and is smiling and cooing! Dr. Punger sent me home with some websites, my dh and I did the research and recognized that this was the issue. We acted pretty quickly because of the pain I was in. Dr. Punger clipped her tongue just before her growth spurt where she nursed every 1.5-2 hours and I'm so grateful! She put on nearly a pound within 10 days."
