My 6 month old has a rash around his eyes. He seems to be his normal self, feeding well, smiling, laughing, playing, etc. Not acting out of the ordinary. He does, however, have a cough that he s had for a couple of months now that does not seem to want to go away, but we ve been to our pediatrician to have it looked at and they say he s perfectly healthy. What could this rash be and should I take him to the doc to have it looked at right away?
