My DD is 15 months and has a whopper of a mouth ulcer on her tongue. She's barely had anything to eat today but lots to drink. It's so painful for her she keeps waking up sobbing and in a sweat. She has a dummy as a comforter but for obvious reasons it's not comforting her much tonight. I've given her Calpol and cold water but it's not helping much. What might help ease the pain for her? I don't have any bonjela to hand and home alone tonight so can't go buy any!
