Anyone caught it from their children? How did it progress - how quickly and where did it start? My DC has had it and stuck things in my mouth (half eaten food, etc) and slobbered on me before diagnosis 
. My mouth felt sore and I have what looks like a white head in my mouth at the top. I genuinely thought I'd be lucky as it's rare in adults. Could this be the start? DC has not had a fever and it's been mild so I'm worried I'll feel fine apart from this.
