If children have all been exposed at the same time and in the same way to a stomach bug, is it usually the littlest who gets it first due to digestive transit time etc? I think I read that ages ago but just wanted to know from your experiences. Have a newborn and 3 other DC, they all got vomited on today by a child with a bug. It was chaos! I'm completely alone, and dreading the onslaught.
