DS woke up at 4 a.m. and threw up. He's been sick about 10 times since. And had diarhea about 3 times. Since he got home from Grandmas at 10:30 he's been asleep most of the day. Is that okay? Should I worry about dehydration? We're giving him toast and pedialyte. This last time he threw up it had been about 2-3 hours since he last threw up so he may be improviing. He's got a mild temp too. Rotovirus made its rounds at his daycare about a week ago but he never had any of the symptoms then. Any advice?
