With stomach virus, its hard to keep from others in the family getting it, due to the contamination. My son, 2 at the time, got it last year about this time. Within a couple of hours of him having it, I had it. Within a couple of hours after I got it, my wife got it. We had a 1 month old too. I quickly called my mother to come to our house and keep the baby from us. She kept her in another bedroom and only brought her out for feedings (breastfed). My wife and I had it terribly, both ran fever afterward and was still drained physically 24hrs later. My son on the other hand was better by the next day. One thing about the little ones, they get over sickness pretty quick. I guess all of the energy they have helps fight it off. Hang in there. Stomach bud is not a common occurrence. Just keep everything clean and sanitized. A good rule of thumb too is to strip down as soon as you get home and take shower and put on clean clothes. I work in education and my wife is a nurse. We are both in it all day ever day so we try to do this as a common practice when it gets the season.
