Stomach Bug???????

Cedie didn't feel very good today. She seemed ok between feedings but she didn't tolerate her feedings well at all. Each time we fed her, she acted as if she were in pain. She was very gassy. She refluxed alot and if her nissen would have allowed, I am sure she would have been vomiting. Each time we opened her tube for a feeding, there was a residual (never happens under normal circumstances) and it had a strange odor and color. I am hoping it is a stomach virus and not something to do with her button placement. We will see how she does in the next day or so.
