Hi just wondering how your dd is today. My 21 month old ds was suddenly sick on Monday and my 17 yo DD was sick later on that evening, so assuming it was a bug. Anyway i'm like you, totally petrified of being sick. I was on my own with my ds when he was sick and had to clean it all up, then he continued being sick on and off for the afternoon. I count the hours down until say about 72 hours have passed before i let myself eat normally. I've just been picking at food for the last 3 days. So far i have'nt come down with the bug and hope very much that i don't either.
I hope it was just the travelling that made you dd sick.
