My daughter has been fussy for a few days and I put it down to her cutting three new teeth in the last 2 weeks. She has been refusing to breast feed for two days but I have been transitioning on to formula as im back at work so again presumed she might just prefer that but only just now as I was changing her and she was crying I've noticed a big mouth ulcer underneath her tongue the size of a 5p, I can only imagine how painful that is for her!!
Is this normal? And could it have been caused by her new tooth that she has there? Should I take her to the GP?
I have given her some calpol and rubbed some bonjela in this evening to try help her sleep .
