My baby has a horrible rash on her face that tends to get worse when she is awake(crying, eating, being held). It started out as a bunch of red bumps and is now very dry looking with some yellow crusty areas. It's on her checks, chin, neck, upper back and chest. We took her to the doctor Thursday and it was diagnosed as neonatal acne but that was before the dryness and yellowness appeared. What could it be and how do I treat it? Should I take her back to the doctor?
