Most tongue tie’s do not cause any difficulty and stretch over time. However a tongue tie may affect a baby’s ability to breastfeed by causing difficulty with latching on.  This can result in nipple discomfort for the mother and some babies will struggle to feed with subsequent issues with weight gain. 

It is also thought that babies with a tongue tie will tend to swallow air causing them to have a lot of “wind” and abdominal discomfort but this may also be due to “colic” or reflux.
