Any reason why your PD said there was no need? The tongue tie release is usually not done by the PD but a paediatric surgeon. How about seeking a second opinion with a paediatric surgeon? My friend’s son had tongue tie that wasn’t obvious at birth, but much later. He would be drenched in saliva, even after 2 years old. Just had the tongue tie released recently. Tongue ties can affect the speech too.
