Hi there, I have a 3 year old daughter who is potty trained but wears a nappy at night. Tonight while putting cream on after her bath I discovered a black mark on her Peritoneum. About the size of a small mole, it doesn t seem to sit on the skin but almost seems right under the surface. It is not perfectly round. It isn t sore or itchy. My mom said she noticed it a couple of weeks ago but because of the position I have no clue how long it has been there. Is this something I should get checked out or am I over reacting? Thank you
