[|Human|] My husband just prepared a bottle using premade formula that he found in the fridge.  However, I believe that this formula was opened more than a week ago.  Once I realized what had happened, I dumped the bottle and open formula and started to nurse her.  I am not sure if I should I be concerned. Are there any risks/warning signs that I should watch for?
[|AI|]  I have gone through the details and understand the cause of your concern. A premade formula was stored without maintaining proper sterility, there are chances of bacterial overgrowth, but generally it will cause curdling of the formula milk which you would have easily noticed. Since that was not the case, I hope you can relax and there is no cause of concern. Diarrhea or vomiting are signs to look out for but if these do not occur, you may rest assured that things are just fine.
