I've been managing to express pretty good amounts of milk so I want to take advantage and freeze some for back up. At the moment I've been expressing 3 or 4 times a day ( as well as bfeeding but dd has latch issues so feeds can take a long time and she gets a bit fractious during feeds and we both generally prefer giving ebm in a bottle) I can express anywhere between 3 - 5 ounces in one session but what I want to know is can you combine milk from different pumping sessions ( but on the same day) in one freezer bag if I put the milk straight in the fridge after I've pumped ? So if I pumped in the morning could I put that in the fridge and then add the afternoons milk to it and then freeze it?
