My DS had his 12-month immunisations (inc MMR) last Friday. This morning he has a terrible spotty-looking nappy rash, plus spotty rashes on both knees, and the odd spot on both feet. The spots are small, kind of pimple-looking, red and close together.

I've no idea what german measles (or measles) look like, other than they are spots. Does anyone know what I'm supposed to be looking for? DS is otherwise happy enough. He's snotty, but has had a cold for the past week. No temp, no vomit, no diarrhoea.

DS has never had nappy rash before (we've been very lucky - he's been an extremely healthy, non-rashy baby!), but I changed a very pooey nappy about 30 mins ago and noticed the rash (he would've only sat in poo for 5 mins max). Does nappy rash come on suddenly - particularly if the poo is acidic??. DH, who gave DS his first nappy rash this morning, didn't notice anything but apparently he was in a hurry, so he didn't look (grrrr - it takes two seconds to look!). So goodness knows if this has brewed overnight, or has come on much more suddenly.

Even if he has nappy rash, it doesn't explain the spots on his knees etc. Our GP told us that one in 10 bubs will get a dose of german measles after the vaccination. Maybe I'm talking myself into this ...?

Anyway, I'm officially confused. Any thoughts welcome.
