I am going on a course next weekend and so DH will need to give DD a bottle of EBM for two of her day feeds.
My (possibly stupid) question is can you mix EBM from different pumping sessions? I get about 3oz per session, and only really get the chance to pump once in the morning. So if I put the 3oz I got this morning in the fridge - when I pump tomorrow can I add the next 3oz to it and then put the 6oz in the freezer?
Also, how do I know how much is enough for a feed? She is over 12lbs and 7 weeks old.
