I only seem to get around to pumping once or twice a day. One pump is for the bottle that DH gives R every night. Then the other pump I am starting my freezer stash.

Tonight I could only pump for 10 minutes, fussy, fussy baby tonight, and I got 3ozs. So I poured that into a bag and put in the freezer.

It seems really wasteful to only put 3ozs in a bag that holds 6ozs. Can I keep in the fridge for another day, then tomorrow pump, pour in the same bag and then freeze?
