yep, both kids had it. The key thing is hand washing. And be sure to throw away any bags if the kis is throwing up in the bags, the vomit is contagious. Wash all of the bed linens and anything that's commonly touched by people, door knobs, hand rails, etc. And be sure to have your DS wash his hands every time he throws up. I know it's alot to do, but if you want to keep from spreading to the whole family, it will work. I'm thankful I never got it. Not that I want my kids to be sick, quite the opposite, but you know, when mom is sick, the world stops for a few days!
