Pleas help ladies: I just made her bottles for the morning and for school. There was one left from today for tonight. I kind of wasn't paying attention and I mixed the bottles up and now I don't know what bottle was made yesterday. What would you do? Give her all the bottles and hope I picked the right one for tonight and she doesn't get sick tomorrow or throw 5 bottles out?? Is it ok to go almost 48 hours in the fridge with powdered formula!? Thank you advance!
