Tongue-tie (ankyloglossia) is a problem affecting some babies with a tight piece of skin between the underside of their tongue and the floor of their mouth (lingual frenulum).
It can sometimes affect the baby's feeding, making it hard for them to attach properly to their mother's breast.
Mouth ulcers are painful round or oval sores that form in the mouth, most often on the inside of the cheeks or lips.
They're usually white, red, yellow or grey in colour and are inflamed (red and swollen) around the edge.
