Hi Liviam, DS2 had it also when he was six months, no idea where he got it from. I took him to the Dr and she diagnosed him straight away with it but also took a swab which came back confirming that it was it. DD and DS1 didn't get it as they had been vaccinated at 18 months, tho I have heard of other kids who have been vaccinated but still got it again. It took DS2 about a week for the spots to go, he was a bit grumpy, but not too bad, slept terribly and to be honest his sleeping went down hill from there. But I just gave him panadol when he seemed to need it and bathed him in pinetarsol and put solosite soothing gel on his spots. For DS2 it seemed to look worse than it was. Good luck. x
