I give my sitter milk for my DD in those Medela 5 ounce bottles that I pump into. I place them in a cooler (the Medela one that came with my PISA) and the icepack it comes with and she keeps it like that in her fridge all day. Would it be better if she took out all of the bottles and stuck them in her fridge that way? Does the cooler help or hinder keeping the bottles as cold as possible?
Any thoughts are appreciated! Thanks!
