M.R.
My son, now 5 months old, was born with a nevus sebaceous on his cheek. While in the hospital, he was examined immediately after birth by a pediatric dermatologist and again before he was discharged. They instructed us to keep an eye on it and have it re-examined at 4 months if it still existed. We are currently working with a pediatric dermatologist and a pediatric plastic surgeon to have it removed.
Did your daughter have a pediatric dermatology consult while at the hospital? If so, follow up with them to see how you should proceed.
If not, start with your child's pediatrician. Show him/her the moles and ask him/her to examine them. The pediatrician may be able to make an assessment or he/she may need to refer you to a pediatric dermatologist.
