Sick Kids

Why is it that when your kids get sick and vomit it's always in the middle of the night??  Now I admit that isn't always the case, but with my kids it sure seems like it is.  There is nothing better than being jarred out of sleep by a child telling you her sister just threw up in her bed!!!  YEEE HAAAA.  Let the good times roll.  Look at the clock 2am.  Great!!
