I've been back to work for just over a month now and have been pumping more than my LO takes to DC. So each week I've been freezing close to 20 oz. I give fresh milk for DC but should I start mixing a few oz of frozen to rotate out the older milk in my stash? I use the one oz freezer trays to make BM sticks so I could just throw one or two in with some fresh milk. What do you do with all this milk!?! Thanks ladies!!
