Tummy Bug

Ugh...we don't often see the tummy bug here at this house, but it has hit . Little Bit threw up 4 times today. It started around 3 am and lasted until about 10 am. She was throwing up and running a low fever, yet between trips to the bathroom she was still singing at the top of her lungs. Annie songs, in particular. "It's a Hard-Knock Life" was the favorite choice today. Appropriate. Quite the performer even when under the weather. She had some crackers and Sprite for lunch and then crashed on the couch for a couple hours this afternoon. She is in good spirits this evening, but still feels warm. Hopefully, the throwing up is over. Now...how do I keep everyone else from getting this bug?
