My kids have a similar thing - they have hand, foot and mouth. Ds got it from daycare and he has spots on his hands, feet an ulcers in his mouth and a temp. DD obviouslt got it from him and she has heaps more spots but they arent just on the hands and feet, they are up her legs and in her nappy area and on her arms too. Its viral and contageous. Its sunday so probaby no chance of seeing a dr but your pharmasist should be able to tell you what its most likely to be. If it is HF&M then no treatment is necessary
