The Best Position to Sleep in When You're Pregnant

Fatigue can hit at different stages of pregnancy, and while every woman is different, most expectant mothers find that they need to sleep more than they did before they conceived. The rules are simple: sleep when you need to, for as long as you need to, and in the safest position for you and your baby. Remember, you may not get much sleep after baby arrives.

Third Trimester: Comfort Is Key

As your due date approaches, you may find it increasingly difficult to find a comfortable sleeping position. Adopt the "SOS" position, but try placing a pillow between your knees to reduce the pressure on them. A special U-shaped pregnancy pillow is designed to fit neatly between your legs. If nighttime heartburn or shortness of breath is an issue, try sleeping with your head or upper body elevated on pillows.

Sleep Survival Tips

Position may not be your only concern when it comes to pregnancy sleeping habits 23. You may find that cramping, restless leg syndrome and frequent trips to the bathroom disturb your sleep. You can't do much about urination, but avoiding carbonated sodas and drinks may reduce leg cramps, says the National Sleep Foundation.
