Protecting the Postpartum Body: Mommy Wrist

Nobody warned me about mommy wrist.

I went to a lactation class before my son was born. They mentioned posture and the strain that feeding positions put on the upper back and shoulders. Good information. But mommy wrist was a completely different level of discomfort that I was not prepared for.

There were days in early postpartum when I could barely hold my baby. When I mentioned it to other moms, so many of them had experienced the same thing. One family friend told me her wrists have never been the same.

This post is the heads up I wish I had received.

What Mommy Wrist Actually Is

The clinical name is De Quervain's Tenosynovitis. It's an inflammation of the tendon sheath surrounding two thumb tendons near the wrist. When repetitive wrist or thumb movements cause irritation, the tendon sheath thickens and swells, leading to pain and tenderness along the thumb side of the wrist that can radiate into the forearm.

Research suggests up to 30% of postpartum women experience symptoms to some degree. That's not a rare condition. That's one in three new mothers.

Mommy wrist often develops in the first few weeks postpartum. New mothers frequently lift, carry, and feed their babies in positions that strain the thumb and wrist. The motion of tucking the thumb under the baby's body while lifting places pressure on the inflamed tendons and worsens the condition over time. Hormonal changes and fluid retention during pregnancy may also contribute to swelling in the wrist, further increasing irritation.

Signs you might have it:

Pain and tenderness at the base of the thumb near the wrist. Swelling in that same area. Pain that worsens when lifting, pinching, grasping, or turning your wrist. Sometimes a catching or snapping sensation. Mothers often notice sharp pain when lifting their babies, turning doorknobs, wringing washcloths, or even texting on their phones.

How It Happens

Just because you can nurse your baby while walking, on a park bench, or in a carrier doesn't mean you should. I learned that the hard way.

New moms find themselves repetitively lifting their baby and positioning their wrist in awkward ways to support the baby's head while breastfeeding, causing suddenly increased strain in the tendons of the wrist and thumb.

The solution that changed everything for me: a U-shaped nursing pillow. You might know it as a Boppy, which is the most recognized brand. Having one in every room you nurse in is not excessive. Ok, maybe a little excessive to have one in every room. But more than one doesn't hurt.

When the pillow is doing the work of supporting baby's weight, your arms, wrists, and hands can relax rather than compensate. One of my friends had one for the bedroom, one for the living room, and one for the car. Smart. You don't have to cart the same one around from room to room. Or remember to grab it before leaving the house.

Proper lifting technique matters too. Instead of picking your baby up under the arms and gripping with your thumb and wrist, try to scoop them up with your whole arm. Slide your hands under their body rather than pinching or grasping.

What Helps

Rest and modify: Easier said than done with a newborn, but reducing the specific movements that aggravate it matters. Use the nursing pillow. Ask your partner to help with lifts when possible.

Wrist splint: Wrist splints worn during activities that typically cause pain provide support and remind you to maintain proper positioning. Some new mothers find wearing splints at night particularly helpful as we often sleep with wrists bent which can aggravate inflammation.

Gentle exercises: Moving the wrist and thumb in the opposite direction of the strain is one of the most effective ways to manage symptoms and restore mobility. The principle is simple. You've been holding your wrist in one position repeatedly for hours every day, and these movements counteract that pattern.

Try these gently and only if they don't increase pain:

Wrist circles: Slowly rotate your wrist in full circles in both directions. Five to ten repetitions each way. This restores range of motion and reduces stiffness.

Wrist extension stretch: Extend your arm in front of you, palm facing down. Use your other hand to gently press the back of your hand downward, bending the wrist toward the floor. Hold for 15 to 30 seconds. This stretches the top of the wrist and forearm in the opposite direction of the feeding position.

Wrist flexion stretch: Extend your arm in front of you, palm facing up. Gently press your fingers downward with your other hand, bending the wrist toward the floor. Hold for 15 to 30 seconds. This stretches the underside of the wrist and forearm.

Thumb opposition: Touch your thumb to each fingertip one at a time, moving slowly and deliberately. This keeps the thumb tendons mobile without straining them.

Radial and ulnar deviation: Hold your arm out with your palm facing down. Move your hand side to side at the wrist, first toward your thumb side then toward your pinky side. Slow and controlled. Ten repetitions each direction.

Tendon glides: Start with your fingers straight. Slowly curl them into a hook fist, then a full fist, then a straight fist where your fingers are flat against your palm. Move through each position slowly. This keeps the tendons moving smoothly through the sheath.

Do these two to three times a day, especially after nursing sessions when the wrist has been in a sustained position. Consistency matters more than intensity here.

If your symptoms are severe, affecting your ability to hold or care for your baby, or not improving with rest and modification, please see a physical therapist or your provider. This is a treatable condition. You don't have to just live with it.

A Note on the Upper Body

Mommy wrist is one piece of a larger picture of postpartum body strain. The upper back, shoulders, and neck take a significant hit during the feeding and holding months too. We're covering that in the next post with specific movements to restore upper body mobility. Because protecting your postpartum body is an ongoing practice, not a one-time fix.
