Hi, DD is 20m and has what looks like a piece of dead skin in her tummy button - it is kind of attached to the inner bit and v hard to get to. I think it has been there for a while and I have tried to fiddle with it but it won't budge and i don't want to yank it. She is awful in the bath and won't "soak" so I think it is just stuck there. It is not inflamed but I am concerned about it just being there. can anyone help?
