Changing the Shape of the Baby's Head During Childbirth (Moulding)

During the birthing process, the baby passes through the mother's narrow birth canal, which can lead to changes in the shape of its head. This phenomenon, known as molding, is a temporary change in the shape of the skull caused by compression of the baby's head during birth. In this article we will look at the causes and consequences of molding, as well as its importance for the health of the newborn and the birth process.

The reasons for molding are related to the adaptation of the baby's head to the mother's birth canal. The baby's head is made up of several individual bones connected by flexible sutures. These sutures allow the head to adjust and change its shape during the birth process. When passing through the birth canal, the baby's head is subjected to strong pressure and compression, which leads to a temporary change in its shape.

Molding can appear in a variety of ways. Often the baby's head will become more elongated and oval shaped, and there may also be a swelling at the top of the head known as a "cap". These changes are usually temporary and gradually return to normal within a few days or weeks after birth.

Molding is essential for a successful birth. The flexibility of the baby's head allows it to better adapt to the birth canal, reducing the risk of injury. In addition, reshaping the head may help the baby move better through the narrow birth canal and reach the vaginal exit.

The effects of molding are usually minimal and temporary. In most cases, the baby's head will gradually return to its natural shape over several days or weeks. However, in rare cases, molding can lead to more serious problems, such as bleeding or skull fractures. These complications require medical intervention and specialist supervision.

It is important to note that molding does not have a lasting effect on the shape of the baby's head. Over time, the bones of the skull close and the head takes on its final shape. However, in some cases the head shape may remain slightly altered, especially if the molding was significant or accompanied by complications.

In conclusion, the change in the shape of the baby's head during birth, known as molding, is a normal physiological process that allows the baby's head to adapt to the environment as it passes through the mother's birth canal. Molding is usually temporary and does not cause serious harm to the health of the newborn. However, in rare cases, molding may be accompanied by complications that require medical intervention.

It is important to remember that molding is a natural and physiological process that helps the baby successfully pass through the birth canal. If you have questions or concerns about the shape of your baby's head after birth, always seek the advice of your doctor. A medical specialist will be able to assess the child’s condition and give the necessary recommendations.

In general, molding is a natural phenomenon that is associated with the process of childbirth and the adaptation of the baby's head to the mother's birth canal. This temporary change in the shape of the head usually does not require special treatment and recovers on its own within a short period of time.



A change in the shape of the baby's head is a physiological condition in which the fetal head is subjected to extreme pressure and becomes flattened. It is a natural, not pathological reaction of a woman’s body to the passage of a baby through the narrow birth canal. Thus, the main purpose is to facilitate labor, although there are quite serious risks of damage to the child’s brain. This process is difficult to perceive, but noticeable to a doctor observing a woman during childbirth - the appearance of roundness of the head in the occipital zone: due to tension, it is pulled into the cranium, taking on the shape of a saucer. After birth, the roundness disappears.
