LO will be one month old tomorrow and in the past few days, has developed what I think is baby acne. But now I am second guessing that as she is starting to show bumps on her upper chest, back, arms, scalp and even ears. It doesn't seem to be bothering her at all. She isn't fussy nor does she have a fever. I am trying to decide whether or not to take her to the pediatrician. Does anyone else have a LO with a similar issue?
