Question for the pumping/haakaa moms

B🌻 • Mama of 3

I’m using the Haakaa and I’m trying to figure out the best way to store the milk after every use. I’m only getting .5-1 oz with each use so I don’t want to use a new storage each time. Or is that the only way to do it? I heard you can’t put fresh milk in with cold refrigerated milk.
