Pregnancy is a very beautiful yet stressful journey filled with joy. A woman's body undergoes major changes; carrying a baby in your body will not be easy. Women feel a lot of discomfort due to pregnancy, and they often seek ways to help get some relief from the discomfort. One simple yet effective strategy is sleeping with a pillow between the legs. This practice can help you in many ways to reduce discomfort and health during pregnancy. In this blog, we’ll understand why this method is beneficial and how it can improve the quality of expectant mothers sleep.

1. Promotes Better Spinal Alignment

As your baby bump grows bigger, the body’s center of gravity shifts, which can cause discomfort and back pain. The added weight and changing body posture can lead to misalignment of the spine. When you sleep keeping a pillow between your legs, it helps in maintaining a neutral position of the spine. This alignment reduces strain on the beck and hips and give you a much needed relief.

A pillow placed between the knees helps to keep the hips and pelvis in a more natural alignment. This positioning can prevent the top leg from pulling the spine out of alignment, which is particularly beneficial for side sleepers—a common sleeping position during pregnancy.

2. Reduces Pressure on the Hips and Pelvis

During pregnancy, the hormone relaxin is produced to loosen pelvic ligaments and prepare the body for birth. While this is necessary for delivery, it can result in pelvic pain and instability. Placing a pillow between the legs distributes weight more evenly, relieving pressure on the hips and pelvis.

This support helps to reduce pain and discomfort in the pelvic region, which can be especially noticeable during the third trimester when the baby's weight is highest. Maintaining appropriate posture and decreasing pressure can significantly improve sleep quality and overall comfort.

3. Improves Blood Circulation

It is very important for the mother as well as the baby that the blood circulation is good. In the second and third trimesters, when the baby is growing fast, the growing uterus can put pressure on the major blood vessels, particularly the inferior vena cava, which runs along the right side of the body and is responsible for returning blood from the lower body to the heart. This pressure can impede blood flow, leading to swelling and discomfort in the legs and feet.

For expectant mothers, it is advised to sleep on the left side with a pillow between the legs, as it can help improve circulation. This position relieves pressure on the inferior vena cava, promoting better blood flow. Enhanced circulation can reduce swelling and decrease the risk of varicose veins, so that you can sleep comfortably at night.

4. Eases Sciatic Pain

Sciatica is an impingement of the sciatic nerve that usually causes discomfort in the buttocks and down the back of your leg. Sleeping in positions that twist your lower back and hips might exacerbate sciatica pain by squeezing the nerve even more.

Sleeping with a pillow between your knees can help relieve compression by keeping your spine straight. This position relieves some of the strain on the sciatic nerve, potentially reducing discomfort and helping you sleep better at night.

5. Enhances Overall Comfort

It is hard to get sleep comfortably during pregnancy, and if you are sleeping comfortably, consider yourself lucky. Frequent bathroom trips, difficulty in finding in a comfortable sleep—all these can make it hard for you sleep peacefully at night. Putting a pillow between your knees adds an extra layer of comfort by cushioning the knees and providing support.


If you are an expectant mother, sleeping with a pillow between your legs can be a game changer for you. It will give you many benefits, such as improved spinal alignment and better blood circulation. This simple technique can help you sleep peacefully during pregnancy.

There are special pillows available on the market that you can put under your knees for better comfort. The Orthopedic Memory Foam Knee & Leg Support Pillow could be an excellent choice for expectant mothers. This pillow is the ultimate in pressure and discomfort relief, providing excellent support for the knees, thighs, and lower back. The hourglass form provides for ideal placement between the knees and the upward thigh area.

As always, it’s important for expectant mothers to listen to their bodies and consult with their healthcare providers about any concerns or persistent discomforts.
