A birthing ball is a large, durable exercise ball used for comfort and dynamic movement throughout the perinatal period. It provides an unstable yet supportive surface that encourages movement, improves posture, and relieves pressure on the joints and spine. Sitting on the ball engages the core muscles and allows for micro-movements, promoting better pelvic alignment than a rigid chair. This inflatable sphere is a valuable asset for expectant mothers seeking an active, comfortable approach to pregnancy, labor, and recovery.
Selecting the Right Size and Setup
The effectiveness and safety of a birthing ball depend on choosing the correct diameter for your height. Individuals under 5 feet 4 inches typically require a 55-centimeter ball. Those between 5 feet 4 inches and 5 feet 10 inches should opt for a 65-centimeter size, and taller individuals (over 5 feet 10 inches) need a 75-centimeter ball.
To check the fit, sit on the inflated ball with both feet flat on the floor, spaced shoulder-width apart for stability. Correct posture is achieved when your hips are positioned slightly higher than your knees, creating a gentle downward slope in the thighs. This alignment tilts the pelvis forward, which encourages optimal fetal positioning and reduces lower back pressure. If your knees are higher than your hips, the ball is too small or under-inflated, restricting pelvic movement.
Using the Ball During Pregnancy
You can begin incorporating the birthing ball into your daily routine as early as the second trimester, though it is particularly beneficial as discomfort increases in the third trimester. Replacing a chair with the ball for short periods improves spinal alignment. The slight instability forces the body to maintain balance, gently strengthening the deep core and back muscles.
The upright posture helps shift the baby’s weight forward, providing relief from lower back pain. Gentle movements like small pelvic tilts and figure-eight motions loosen the hip joints and alleviate tension in the hips and pelvis. Regularly practicing these movements can help encourage the baby to settle into an anterior position, which is favorable for birth. Start with 10 to 15 minutes of use and gradually increase the duration.
Using the Ball During Active Labor
The birthing ball is a powerful tool once active labor begins, offering a comfortable way to remain upright and mobile. Sitting on the ball allows gravity to work in your favor, assisting the baby’s descent. Moving freely on the ball reduces labor pain by distracting the nervous system and continuously shifting pressure off the sacroiliac joints.
While sitting, you can execute slow, controlled circular movements or figure-eights with your hips to encourage cervical dilation and pelvic opening. This rhythmic motion helps the baby navigate the curves of the pelvis as they descend.
For managing intense back labor, kneel on the floor and lean your upper body and head over the ball, which is placed in front of you. This hands-and-knees variation takes pressure off the spine and provides cushioned support for resting between contractions.
Another effective technique involves using the ball to support a standing or squatting position, which maximizes the pelvic outlet. By placing the ball against a wall or hospital bed for counter-pressure, you can lean into it while maintaining a wide stance. This provides a stable anchor, allowing you to rock or sway through contractions. Movement and position changes throughout labor are paramount. The ball makes it easier to transition between resting and active positions without lying flat on your back, keeping pelvic joints mobile and encouraging the baby to rotate into the best possible position for delivery.
Postpartum Applications
The utility of the birthing ball continues seamlessly into the postpartum recovery period. Sitting on the ball provides a much gentler seating option than a firm chair, which is beneficial if you are experiencing perineal pain or tenderness. Its soft, yielding surface avoids direct pressure on stitches or sensitive areas.
Once cleared for gentle activity, the ball can be used for introductory core and pelvic floor recovery exercises. Simple bounces and pelvic tilts re-engage the deep abdominal muscles and promote circulation to aid in healing. The ball is also widely used as a soothing mechanism for a fussy newborn, as gently bouncing while holding the baby mimics the rhythmic motion they experienced in the womb. This low-impact action can calm a crying infant and offers a comfortable way for the parent to provide comfort.
