Nose Suction Thingie
Pack for the hospital:

Pillow
Maxipads (They have them, but they are TERRIBLE). I recommend these: http://www.kotex.com/NA/products/u-by-kotex-cleanwear-ultra-thin-heavy-flow-pads-with-wings/90394 . Go ahead and get a pack or two, so no one has to go get them later.

Change of clothes or two for Dad
Going home outfits

Also, I don't know if everyone does this or if just we did, but Shawn brought a couple dozen cupcakes on Day 2 in the hospital, one dozen for L&D, one for post-partum nurses. They REALLY appreciated. And I got a good room :)
