Birth Labor/birth Also: OP

Occiput posterior

Abbreviation: OP

Occiput posterior (OP), sometimes called the sunny-side-up position, means your baby is head-down but facing your belly button instead of your spine. This makes it harder for the baby's head to fit through your pelvis efficiently. Labor can be longer and more intense, and many women feel strong, persistent pain in the lower back rather than the abdomen. Some OP babies rotate on their own during labor. Hands-and-knees positions, walking, and swaying can encourage rotation. In some cases, the doctor may assist with instruments or recommend a caesarean if progress stalls.

What This Means for You

Understanding Occiput posterior is an important part of your labor/birth journey. When preparing for birth, understanding this term helps you discuss your birth preferences with your midwife or OB-GYN and know what to expect in the delivery room.

Good to Know

Spending time on all fours or leaning forward on a birth ball in late pregnancy and early labor can help encourage your baby to rotate to the OA position. Discuss position options with your midwife at KKH or NUH.
