With the freezer bags, it's a matter of preference. We prefer the Lansinoh bags because they have a colored zipper and a second zipper, which seems more secure to me. They also are thicker, which I like because we're not sure how long we'll be waiting and I don't want the milk to freezer burn or anything.
the Lansinoh nipple moisturizer is a must, because you don't want to be sore and cracking and not have that around.
For a cover-up, you can use anything you'd like. A blanket, a sling, a shawl. Some babies don't like their faces covered while they're nursing (and it's good for their eyes to be able to see you) so just keep that in mind. Once they're a little bigger, the baby's head plus the nursing bra does a good job of covering up the "private" part of nursing.
It's good to get stuff ready now, cuz once all those babies come, you won't be able to think, much less go shopping! Good luck! <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
