Why?

Why is it that kids always get sick late at night? I don't think any of my kids have ever thrown up during the day. They will complain about not feeling well, but still run wild. Then they get in bed and sleep for a few hours then it hits. Oh the joy of cleaning up puke in the middle of the night. I must say I've been lucky and my kids don't get stomach flu's very often, hopefully this one doesn't go thru the whole family. Haley is feeling much better this morning though and kind of liked the attention she got last night. Cuddling with Mom and drinking sprite is kinda fun sometimes.
