"Week 37: A Special Rub
Anxiously waiting for the big day to arrive? Don't just sit there — massage your perineum! (Say what? Trust me, there's good reason for this piece of advice.) Perineal massage may help to gently stretch your perineum (that area of skin between your vagina and rectum), which in turn can minimize the "stinging" that occurs when baby's head crowns during childbirth. It may also help you avoid an episiotomy and tearing. Here's how to massage your way to an easier (and looser, if you're lucky) labor: First make sure your hands (or your spouse's, if he'll be taking on the task) are clean and nails trimmed. Next, lubricate your thumbs or index fingers (here's where the K-Y jelly can come in handy — literally — again) and put them inside your vagina. Press down (toward your rectum) and slide your fingers across the bottom and sides of your perineum. You can do this daily until D-day (and you can even continue the good work — or have your practitioner take over — during labor itself!)…or not at all if it makes you feel uncomfortable. "
