My granddaughter did that to me a few years ago. I"m a nurse so I've cleaned up lots of emesis (a medical word for vomit - why is there always a medical word for everything??), but it is different when it is all over you!!! We were traveling and staying in a hotel - she vomited so many times, and when she was asleep, she didn't know it - she'd just vomit in her sleep. So, I had to sleep with her holding a towel under her little chin. It was a pretty sleepless night. We were supposed to ride the train home the next day - about a 10 hour trip. We (my daughter, my mom and ) were so afraid that we'd all get it because we'd all be maximally exposed (LOL!). We didn't want to be puking on the train, so, we rented a car to make the trip home - we knew we could stop when we needed to, take turns driving if we were all sick, and make it home some how. Interestingly, none of us adults got it. Abigail was fine the next day, but she must have thrown up 10 times.
