the HV says it could be just his skin coping with airborne pollutants, or heat rash - it is on his face, neck and top of shoulders, tiny red/uncoloured bumps. Individual prickles seem to disappear fairly quickly but the overall effect is staying the same. The only thing we can think of that touches his face but not so much other areas is us! We aren't using bio detergents or anything other than plain old soap on our own hands. Any suggestions for a cream/lotion? Or do we just have to wait for his little pizza face to clear itself up...?
