So I have been working on my stash for my breast milk for when I start back at work in a month. I am wondering, how much milk do you put in each storage bag? Do you mix your pumped milk (meaning 4 oz from morning session, 4 oz from next session, etc)? If you out more milk in each bag than what your baby eats at one sitting, how do you portion it. Any tips and tricks are welcome. I am currently putting about 4-6 oz in each bag and laying flat to freeze. I have about 250-300 oz frozen currently and am pumping about 10-15 oz per day. Tell me your secrets! I like to be as organized and efficient as possible! Share pictures if you have them!
