Wow, it sounds like you have plenty of milk! So, that's a wonderful thing, and my guess is, you have figured out how to pump and nurse and make sure there's enough to go around, and that probably won't change. I WOULD start using some of the frozen soon, if it's from July. It should be fine in the deep freeze, but I think you're starting to get to the point where it's not as good. On the other hand...fresh milk is MUCH better for baby (freezing destroys some of the nutritional value of breastmilk), so if you're confident of your supply--and you're already at 7 months--I would keep feeding her fresh milk and just chucking the frozen milk. I know it's frustrating, but chalk it up to "I stored up just in case" and call it good! I know when I was pumping and working full time, I really noticed it when I got sick. Pumping, I didn't get nearly as much milk, and I assumed that's the way it was. But, with #2, I was home and, even when I was very dehydrated with food poisoning, my milk supply was still my body's #1 priority. Anyway--it's probably good to keep some frozen "just in case" but you should probably either use or toss the stuff in your freezer from July; I think four months would be about my limit, even w/ the deep freeze.
