A transverse lie position is when your baby lies horizontally in your uterus. This means the baby’s head can be on one side of the mother’s body and the feet on the other side instead of the head in an up or down position. As the pregnancy advances, the baby grows and moves in the womb. Towards the end of pregnancy, most babies move to a head-down position, and this is helpful in normal vaginal delivery. Less commonly, some babies may not take up common positions and require cesarean sections to deliver them. Read about the causes, types, risks, and other factors related to the transverse lie position.
What Is A Transverse Baby Or Transverse Lie?
When the baby lies horizontally in the uterus, instead of an ideal vertical or head-down position, it is called a transverse or longitudinal lie. In simple terms, it can be said that the baby is lying sideways, with its head either on the left or right side of the uterus. It is rare and could occur in one among 300 pregnancy cases (1). The position is normal during the initial stages of pregnancy or till 26 weeks. However, it could be considered abnormal when the due date is nearing. With the baby in such a position, it is not possible to go for a normal delivery. The baby may come to the sideways position due to different reasons.
What Are The Causes Of Transverse Baby Position?

The ultrasound also confirms the same. The exact transverse lie position of the fetus can be determined through shoulder presentations.
What Are The Transverse Lie Positions?
There are four shoulder presentations of transverse lie (7): As the transverse baby bump position is not considered normal, there could be certain risks when delivering the baby.
What Are The Risks For The Baby In Transverse Lie?

Frequently Answered Questions
1. What happens if the baby cannot be turned?

However, if the first twin is delivered normally, then the second twin might come to a transverse position. In this case, doctors try to turn the second baby through internal cephalic version (manual intrauterine procedure to change transverse lie to breech) or external cephalic version and then decide whether or not to schedule c-section (4).
3. How long can a baby stay in the transverse lie position?
Most of the babies settle down in a normal position or the head-down position by the end of the second trimester or beginning of the third trimester. It is usually between 28 to 30 weeks. However, some babies also move around after the beginning of the third trimester, and tend to take the normal position by the 31st or 34th week.
