No because she as cutting her tooth she kind of went off food and was only drinking milk and the occasional fruit pouch all off which she's had before and never had an issue with. X
Does she use a dummy?
@Lottie yes she does.
I was about to ask if she uses a dummy. My son got this occasionally especially when he was teething and it was just irritation from all the slavering and his skin not airing out under his dummy
Looks like it could be from the dummy.
Has she tried any new foods? That looks a bit like an allergic reaction to me rather than a teething rash but I could be wrong x
