........ and in that case, the mum doesn't need to worry or do anything. It recedes as the tongue grows longer and bigger.
Due to many mums complaints and anxiety over tongue-tie, many charlatans often offer to do the surgery and often create more problems for the baby including bleeding, infections e.t.c. Please make sure only the professionals see your baby and if the doctors say don't worry, don't go behind to meet charlatans to do it. Some hospitals also take undue advantage of some unsuspecting mums by doing the surgery unnecessarily just to make money off them.
Tongue tie doesn't cause dumbness or affect speech except for exceptionally thick one which doesn't allow the baby's tongue to lift which may rarely affect speech, in such cases qualified paediatric surgeons can do a simple surgery to free it. In fact, this is done around age 1 to 2 years.
