Flu season

Our kids passed around the stomach flu about a week ago. First it was Talon, then Jaren, then Angelique, then Beauchene. Jileigh, Safia and Matt only got a touch of it. I think I got a touch of it too. I wonder if there is medical explanation as to why kids always throw up about an hour after everyone is asleep, and they can't possibly make it out of thier beds first! Thank goodness for washing machines and extra sets of bedding. Who needs sleep, anyways?!
