How old is the baby? First of all, hormones in newborns are off for a while. Think of all the parents who don't take photos of their newborns around age 3 months when the baby acne is in full bloom!
Second, you don't worry about such things anyway - it's just cosmetic and you just wait and see. Don't worry about other people's opinions - a baby won't remember or be scarred by anything anyone else says.
Third, you really need to be in regular touch with your doctor's office. There's a nurse question line and a nurse will call you back for non-emergency things like this.
Fourth, make a list of things like this that are not urgent and bring them up at the next check-up or weight check. It's easy to forget things when you're in the exam room, so just keep a running list on your phone or on a pad on your refrigerator, whatever works for you.
