Why might you need extra back support?
If you’re pregnant, breastfeeding, and /or recovering from a cesarean section delivery, lying on your side is an important component of your rest.
Pregnant woman and breastfeeding moms, for a time, have a hormone present in their bodies called relaxin. Relaxin can cause symptoms such as reduced stability in the pelvis and joints. So when both pregnant side-lying sleepers and side-lying breastfeeding mothers stay laying down on their side, there is increased discomfort in their joints, pelvis, and back.
Also, mothers who experienced cesarean sections at birth also struggle to nurse their babies accross the front of their bodies as they recover from surgery. Extended side-lying can lead to much physical discomfort for these women.
