Hello? My docs office is closed. He has a mild milk allergy which we thought was the cause of the rash. He had runny diapers. He then got a rash, red, not raised, splotchy. It was on the tops of his thighs. Then his cheeks and his trunk. It is the brightest on his arms and cheeks. No fever. And he hasn't had milk now in almost 2 days but the rash seems to be getting brighter.
