The best sleep position during pregnancy is “SOS” (sleep on side). Even better is to sleep on your left side. Sleeping on your left side will increase the amount of blood and nutrients that reach the placenta and your baby. Keep your legs and knees bent, and put a pillow between your legs. If you find that you are having problems with back pain, use the “SOS” position, and try placing a pillow under your abdomen as well. If you are experiencing heartburn during the night, you may want to try propping your upper body with pillows. In late pregnancy, you may experience shortness of breath. Try lying on your side or propped up with pillows. These suggestions may not sound completely comfortable, especially if you are used to sleeping on your back or stomach, but try them out. You may find that they work. Keep in mind that you may not stay in one position all night, and rotating positions is fine.
