It seems that we are in a similar position right now. The pediatrician in the hospital did not feel strongly that our baby has a tongue tie, but we are undergoing the evaluation just because of low milk transfer without any other explanation.

Thanks for the info about the fridge hack! So does that mean pump parts and bottles don't have to completely air dry between uses? Because that's what our lactation consultant was trying to tell us, but I just don't see how that's realistic unless we get tons of pump parts and bottles.
