Hi i just noticed this was on my daughters face has anyone ever experienced this on their child or maybe could help me figure out wat this is. It doesn’t seem to bother her at all she’s 4.5 months and teething.

I’m 19 and This is my 1st child so I’m not quite sure if i should take her to the doctor
