Also, don't forget to have LOTS of maxi pads and breast pads stocked up. (The Lansinoh pads are great) It will make your life much easier not having to worry about running out of those 2 items. As far as baby goes, I've found bibs to be quite useful because they can prevent spilled milk on the clothes, therefor less laundry!
You will quickly create a routine at home and will use things you didn't expect to, and not use things you thought you would.
