Get yourself a small cooler bag and some blue ice. Place the blue ice and the frozen breastmilk in the cooler. Keep the open cooler bag in the freezer. When the power goes out just run over to the freezer and close the bag. And when the power comes back on just open the bag again. Those puppies are so well-built that if you keep the bag closed all the time the cold freezer air will be kept out of the bag and the blue ice and the breatmilk will eventually thaw.
19 bags so far, baby. Booya!
Lansinoh is the best! I love their disposable nursing pads. I have their washable ones too...but I think those are best for when my supply lessens. I love their milk storage bags, and I love that each box of nursing pads comes with two free storage bags - not with the ultrasoft pads though.
A few of the boxes that I've recently bought have actually come with a sample of Lansinoh's Clean & Condition Cloths (baby wipes). I'll be using those in the diaper bag, but I don't think I can afford to buy them regularly.
But I do think I'll need to get me some of these before I go back to work.
