What part of the baby comes out first?

During the wonderful journey of pregnancy, one of the most anticipated moments is the birth of the baby. As expectant parents prepare for this momentous event, it’s important to have an understanding of the position of the baby during birth. Knowing which part of the baby comes out first can provide valuable insights into the birthing process and help expectant parents make informed decisions. In this blog post, we will explore the fascinating topic of the baby’s position during birth, focusing on the common occurrence of occipito anterior position.

Occipito Anterior Position

The majority of babies are born in what is known as occipito anterior position. This means that they are facing downwards, with their back against the mother’s stomach and their chin tucked in on their chest. In this position, the baby’s head is the first part to emerge during birth. The term “occipito anterior” refers to the fact that the back of the baby’s head (occiput) is facing towards the front (anterior) of the mother’s pelvis.

During occipito anterior position, the baby’s face aligns with the curve of the mother’s sacrum, providing an optimal fit for the birth canal. This position allows for a smoother and more efficient delivery, as the baby’s head is able to navigate through the pelvis with minimal resistance.

Process of Birth

To better understand the position of the baby during birth, let’s briefly examine the stages of labor. Labor is divided into four main stages: early labor, active labor, transition phase, and the pushing stage.

Early labor: During this stage, contractions begin to gradually increase in intensity and duration. The baby is positioned in the upper part of the uterus, with their head generally not engaged in the pelvis yet.

Active labor: As labor progresses, contractions become stronger and more frequent. The baby begins to descend into the birth canal. In occipito anterior position, the baby’s head will be facing downwards, with their back against the mother’s stomach.

Transition phase: This is the final stage of labor before the pushing stage. The baby’s head rotates slightly as it reaches the pelvic floor, adjusting its position to align with the curve of the birth canal.

Pushing stage: During this stage, the baby’s head emerges first, followed by their shoulders and the rest of their body. In occipito anterior position, the baby’s head leads the way, making its appearance first.

Factors Influencing the Baby’s Position

The position of the baby during birth can be influenced by various factors, both maternal and fetal. Maternal factors include the size and shape of the pelvis, the position of the uterus, and any previous pregnancies and births. Fetal factors include the size and position of the baby, the placement of the umbilical cord, and the location of the placenta.

It’s important to note that while occipito anterior position is the most common and optimal position for birth, not all babies assume this position. Some babies may be in occipito posterior position, where their back is against the mother’s spine. This position can present challenges and complications during labor. Additionally, a small percentage of babies may be in a breech position, where their buttocks or feet are positioned to exit the birth canal first.

Impact of Baby’s Position on Labor and Delivery

The position of the baby during birth can have a significant impact on the progress of labor and delivery. In occipito anterior position, the baby’s head provides optimal pressure on the cervix, aiding in its dilation. This can result in a smoother and faster labor. However, when the baby is in occipito posterior position or breech position, labor may be more challenging and prolonged.

Certain complications may arise when the baby is not in the optimal position. For example, occipito posterior position can lead to a longer and more painful labor, and may increase the likelihood of medical interventions, such as epidural anesthesia or even a cesarean section. Breech-positioned babies also require special attention and often necessitate specific delivery techniques or even a planned cesarean section.

Techniques to Encourage Optimal Fetal Positioning

While the position of the baby is primarily influenced by the baby itself, there are some techniques that expectant parents can try to encourage optimal fetal positioning:

Maternal positioning and movement: Engaging in activities that promote good posture and encourage the baby to settle into the occipito anterior position can be beneficial. Sitting on a birthing ball, avoiding reclining positions, and regularly changing positions during labor can aid in optimal positioning.

Pelvic tilts and exercises: Performing exercises that strengthen the lower back and pelvis, such as pelvic tilts and squatting, can help create a favorable environment for the baby to settle into the correct position.

Use of birthing aids and tools: Certain birthing aids, such as a birth stool or a birth pool, can also promote an optimal fetal position. These aids provide support and encourage the baby to naturally align with the birth canal.


Understanding the position of the baby during birth is crucial for expectant parents as they prepare for the arrival of their little one. The majority of babies are born in occipito anterior position, with their head leading the way during delivery. Factors such as maternal and fetal characteristics can influence the baby’s position, and alternative positions like occipito posterior or breech can pose challenges during labor.

By recognizing the importance of optimal fetal positioning and implementing techniques to encourage it, expectant parents can increase the chances of a smoother and more efficient labor. It is recommended for expectant parents to consult with their healthcare providers to discuss the optimal position for their baby and receive guidance on techniques that can be helpful during labor. With this knowledge and support, parents can feel more confident and empowered as they embark on the incredible journey of childbirth.
