My 14 month DS2 has developed a couple of patches of a rash which is a red circle with a red dot in the middle. Only 2 atm but they are the size of an old 50p piece (the bigger ones). My first reaction was that he had ringworm but now I'm wondering if it could be Lymes disease (the one commonly transferred by ticks). I'm taking him to the doc tomorrow (we are in NZ) but what do you guys think?
