Tongue-tie is where the skin joining a baby's tongue to the bottom of their mouth is shorter than usual. It sometimes makes it harder to breastfeed.
Your baby may have tongue-tie if they find it hard to breastfeed. They may struggle to attach to your breast and might make your nipples sore.
Tongue-tie does not always need to be treated. If it stops your baby breastfeeding, a simple procedure can be done to cut the skin under their tongue.
