Get a pedi. It feels so good to see your feet again and have ten look pretty too :)
You can learn how to crochet or do projects with your other kids... go out and get some beads and pretty yarn and have them make gifts for the new baby. :) tell them it'll be the baby's first birthday present ;)
Set up the nursery, go get a massage, get your hair done. Anything that will make you feel as beautiful and relaxed as possible.
