#AskTheExpert hi doctor can u please advise how to store expressed breastmilk. how many hours can the milk be outside without being refrigerated. thanks

A. Pumped milk can stay out up to four hours.” ... In fact, you can grab this same bottle three hours later and continue pumping into it. Or, if you're power pumping to increase your supply, you can pump into the same bottles multiple times within the four hour window
