Am leaving 11 week old DD with my mum on Sat whilst we go to a wedding, anticipate being away about 8 hours. Planning to leave enough EBM for 3 feeds of 4oz (will this be enough?) each but have no idea really how much she'll take at each feed. If she leaves say a couple of ounces in a bottle would it be alright to save it for later in the day? Also should you warm it up again? Oh questions, questions.....
