Gradually increase your activity as your strength returns and you begin to feel better.  Careful, slow stair climbing and reasonable lifting are acceptable.  However, you should not allow yourself to become fatigued.  Be sure and allow yourself rest periods as your baby rests.  Let the way you feel and the obvious limitations of fatigue and discomfort be your guide.  You may ride in a car a reasonable distance at any time, and you may drive once you are pain free without the use of presciption pain medications as these may alter your reaction time.
