Hello, I have a 8 week old son and from 2nd week I've been pumping once a day to get a good frozen supply incase of emergencies. I can't pump more than once as my DS refuses a dummy so uses me for comfort and food but I don't mind. My freezer needs defrosting as DH left freezer door partly open for I think an hour so it's now all frozen inside and am struggling to pull draws out. I'm wondering how to save my frozen milk if u have any advice. Is there a product or anything anyone has used to stop defrosting. Don't wanna lose my back up supply x
