How should I position myself for sleep during pregnancy?

To minimize discomfort during sleep:

• Favor your side. Some research suggests that lying on your left side can help improve blood flow to your baby and to your body. Also, try to keep one or both knees bent. Don't worry, however, if you wake up in a different position.
• Use pillows. To prevent discomfort, consider using pregnancy or support pillows between your bent knees, under your abdomen and behind your back.
• Elevate your head. Elevating the head of your bed can prevent or decrease heartburn or snoring.
