I EP and have been since we came home. I pump twice what he needs and he is 5 weeks Monday. That being said I have a huge freezer stash a,ready. My question is since that the milk changes as he grows will my milk still be good to him in a few months if I decide I'm done pumping, or need to do it less or whatever the case maybe? Since the milk is only one month old say come month 6 will it still satisfy him?
