Tummy Troubles

Our house has been hit by tummy troubles. Last week Sara woke and was so sick. She couldn't keep anything donw or in. When you have 4 kids things pass through them quickly. So later that week Eli and Jaron came down with a tummy bug. Well poor Kristofer, who already has issues with pottying is now sick with the tummy bug and Eli has it to. I have bleached and lysoled every door knob, cleaned all sheets and have done everything I can to get the "bug" out of the house. Hopefully thistoo shall pass. I feel so helpless when the kids are sick. I would rather it be me than them.
