Moving around, standing and squatting are some of the best positions.
There is no one best position. In fact, most women end up changing positions frequently during labor. Let your body be your guide. It is best not to lie down for too long. Studies have shown that women who tended to walk or stay upright during early and active labor reduced their labor time by one hour.
Sometimes, a medical condition will dictate what's best for you and your baby. If you have any complications that require continuous monitoring and you need to stay tethered to a monitor by a cord, your ability to move around will be limited. Occasionally a baby's heart rate will indicate that he prefers you to be in one position or another.
