Cloth pads or cheap flat cloth diapers are soo much better than disposable pads at home, those keep in moisture and don't let you heal.
A million baby blankets for every use you can possibly imagine - especially under you and baby in bed so milk, spitup, baby pee, etc doesn't make you have to wash the sheets every time there's a spill.
Whatever clothes you'll want to wear, try to make sure you won't have to do laundry especially if you're the only one who knows how.
Hydrogen peroxide for blood stains (pp bleeding and the initial stuff if you have a homebirth)
Disposable dishes, including cups
Juice...Lots of juice, and quick snacks. I went through a half gallon to a gallon of orange juice a day for some reason my first week pp. And my blood sugar would drop in moments without warning, to the point I couldn't lift my arms let alone get up. It was weird.
