How your baby’s position can influence labor and birth

Susan - Chief of Healthcare at The Baby Academy

As you move through your second and third trimester, you may start hearing your healthcare provider talk about your baby’s position. This refers to how your baby is positioned in the uterus as you get closer to labor and delivery, and it’s one of several things your care team will monitor in late pregnancy.

Most babies will naturally move into a head-down position before labor begins, but it can be helpful to understand the different positions and what they mean. It’s also completely normal for babies to change positions frequently earlier in pregnancy, especially before the third trimester.

Understanding baby’s position in the womb

There are three main positions your baby may be in:

Vertex (head-down position)
This is the most common position and is typically considered the ideal position for a vaginal birth. In this position, your baby’s head is down toward the birth canal.

Breech position
In a breech position, your baby’s buttocks or feet are positioned to come first. There are different types of breech presentation, and in many cases babies will still turn on their own before labor begins.

Transverse position
This is when your baby is lying sideways across the uterus. It is less common in late pregnancy, and most babies will naturally shift out of this position as space becomes more limited.

What can influence positioning

There are several factors that can influence your baby’s position, and most of them are completely out of your control. These can include the shape of your uterus, the location of the placenta, the amount of amniotic fluid, and your baby’s own movements and space.

Because of this, it’s important to remember that baby’s position is not something you can fully control or “fix.” Instead, the focus is on supporting your comfort, movement, and overall wellbeing during pregnancy.

Tips to encourage optimal positioning

While there is no guaranteed way to change your baby’s position, some gentle movement and posture habits may help support optimal positioning in the second and third trimester.

You can try:

  • Staying active with regular movement throughout the day, rather than sitting or lying for long periods
  • Using a birthing ball or sitting with your hips slightly higher than your knees when possible
  • Avoiding long periods of sitting cross-legged
  • Going for walks or gentle swims when you feel able
  • Sleeping on your side with a pillow between your knees for support and comfort

These are not about forcing a specific position, but about encouraging mobility and creating space for baby to move naturally.

When to speak with your provider

Most babies will move into a head-down position by the time labor begins. If your baby is breech or transverse later in pregnancy, your doctor or midwife will monitor this and talk through next steps with you.

In some cases, they may discuss options such as an external cephalic version (ECV), which is a procedure used in some pregnancies to try to gently turn the baby into a head-down position. Your provider will explain whether this is appropriate for you and what the safest plan is based on your pregnancy.
