Some bottles of bm got mixed up in the fridge and one that was previously frozen and should have been dumped wasn't. So dd had some of it and has since thrown up, has a 101 fever, and is lethargic. I just tasted the offending bottle and it is definitely spoiled (I'm surprised she even drank it!) Now she's nursing. My gut tells me that the fact that she threw up and has a fever means her body is dealing with it appropriately and she'll be fine. But should I worry? Any suggestions to help her feel better?
