In this guide, we explain what new mothers should know about Mother's Thumb.
Why Does Mother’s Thumb Develop After Childbirth?
Mother’s Thumb often develops due to body changes after pregnancy and the repetitive hand movements involved in caring for a newborn.
Repetitive Baby Care
Daily baby-care activities can place additional strain on the thumb and wrist. Frequently lifting your baby from a crib, car seat, or changing table requires repeated hand and wrist movements throughout the day. Over time, these motions can irritate your tendons and lead to pain.
Hormonal and Body Changes
During pregnancy and after birth, hormonal changes can affect tissues, making the wrist tendons more sensitive. Some women may experience fluid retention during pregnancy and after childbirth, which can increase pressure around the tendons.
The Way You Hold Your Baby
The way you hold your baby also matters. Certain hand positions add pressure on the tendons.
- Bending your wrist while holding your baby
- Supporting the baby’s weight mostly with the thumb
- Keeping the same hand position during feeding
- Repeated gripping and twisting in daily care
What Are the Symptoms of Mother’s Thumb?
The signs of Mother’s Thumb usually develop slowly and may feel stronger with your daily baby care. You may notice:
