Your partner, of course, isn't as physically beaten up as you are right now, but he or she is probably pretty anxious, too. It's hard to stay in a constant state of preparedness, and it's taking a toll on both of you. Just remember to be supportive of each other, and try to enjoy the last days you have together all alone. Some day in the very near future, it's going to seem like an impossible luxury to do something as simple as sitting on the couch and having an uninterrupted conversation.
Something your partner might enjoy doing this week is making a music playlist for the hospital. You might appreciate a lot of tunes for what will likely be a very long day. You never know how labor may go and what your mood will be, so why not have a bunch of options at your disposal? Include a slow, soothing song at first and then a few tunes to pump you up to get through those contractions. Your better half will probably enjoy choosing music that will inspire and energize you, and if you find you have absolutely no tolerance for any tunes while you're in the thick of things, you can always listen when you're relaxing with a precious baby in your arms.
