So I'm trying to build up my stash for when I go back to work. I'm pumping say 5 oz bottles and putting them in the freezer bags, but when I pull them out to use them, thaw them and put the milk in a bottle it measures out to like 4 oz. I know they lose some nutritional value when frozen but an ounce? My bags aren't leaking, I know that...I've even double bagged them to make sure. Anyone know what's up. I feel like it's an uphill battle I'm not producing that much so any milk lost is not making me happy.
***also after doing some research it looks like I might have excess lipase. Could that be a cause? Baby doesn't have any issues with BF or taking a bottle...
