-stuff a sock with rice. it can be heated in the microwave or frozen in the freezer for a great pack to assist during labor - especially with lower back pain!!
-peppermint oil - for all you pukers! lol. sniff it when you feel nauseous and it should help the nausea go away.
-honey - cover your super soaker pad with it and wear it around for a bit. it has natural healing properties and is supposed to feel good too. obviously, you'll want to do this one before you plan on taking a shower.
-newborn diaper - slice open back end to reveal the pocket that holds all the soaking jellies and whatnot... fill with ice and use it as an ice pack.
hmm. i think that's all i have. :( definitely need more! bring 'em on mamas!!
