My 12mo ds has a rash ALL over his body. It started on tues on his tummy and back. I thought it most likely a heat rash but on weds it had spread to his arms and legs. By thurs (today) it was all over his body, on backs of his hands, his face and feet. I took him to the dr and saw a nurse practitioner who suggested it was just a viral infection. She said that it should clear up in a couple of days. I'm just concerned. Watching him in his bath tonight it looks awful. He doesn't have a temp and seems generally quite happy in himself. He is slightly off his food but is drinking plenty of water and has plenty of wet nappies. His poos are slightly loose and a little pale but other than that he seems ok. Has anyone gone through something similar with their LOs?
