What is the definition of Newborn Head Molding?

Newborn head molding is an abnormal head shape that results from pressure on the baby's head during childbirth.

What are the alternative names for Newborn Head Molding?

Newborn cranial deformation; Molding of the newborn's head; Neonatal care - head molding

INFORMATION

The bones of a newborn baby's skull are soft and flexible, with gaps between the plates of bone.

The spaces between the bony plates of the skull are called cranial sutures. The front (anterior) and back (posterior) fontanelles are 2 gaps that are particularly large. These are the soft spots you can feel when you touch the top of your baby's head.

When a baby is born in a head-first position, pressure on the head in the birth canal may mold the head into an oblong shape. These spaces between the bones allow the baby's head to change shape. Depending on the amount and length of pressure, the skull bones may even overlap.

These spaces also allow the brain to grow inside the skull bones. They will close as the brain reaches its full size.

Fluid may also collect in the baby's scalp (caput succedaneum), or blood may collect beneath the scalp (cephalohematoma). This may further distort the shape and appearance of the baby's head. Fluid and blood collection in and around the scalp is common during delivery. It will most often go away in a few days.

If your baby is born breech (buttocks or feet first) or by cesarean delivery (C-section), the head is most often round. Severe abnormalities in head size are NOT related to molding.
