I was trying to find my answer on KellyMom, but didn't see anything. So, when I want to freeze my milk, I have bags to put it in. However, those go up to 6 oz. and I just pumped 1.5. What should I do? Just refrigerate until the bag is full? I don't think it sounds right to freeze and add as I go. But, I also don't want to waste 4.5 oz. of a bag, especially when DD will eat 3-4 oz at one time. Help!
