Today I have one week with my baby and yesterday I started to notice she was starting to get white stuff on her mouth. I asked her doc. ( first time meeting her doc but will be switching) and she just said to bring her in on Friday. Today she has a complete full white tongue, on the top of her mouth and a little on her lips. I will be calling to see a doctor I used to see. But what can I do? I'm really concerned. Should I be extremely worried?
