Tongue tie

What we do

We treat babies aged eight days to 26 weeks who have a condition called tongue-tie. This means they have a tight piece of skin between the underside of their tongue and the floor of their mouth that makes it difficult for them to breastfeed.

We carry out a small operation which releases their tongue and allows them to latch on and breastfeed properly.

Babies are referred to us by their breastfeeding specialist. They can also be referred by their GP, but they must first be assessed by your breastfeeding specialist.

For details of your breastfeeding specialist, please see the inside cover of your baby Red Book.
