Most of the time, a baby’s head will even itself out. Flat head syndrome can even start before birth if theres pressure on the babys skull from the mothers pelvis or a twin.
Some skulls accept the deformation (compliance) and allow an easy delivery, while others do not deform easily (non-compliance).” “Fetal skull molding is no more visible in most newborns after birth. Babies skull bones are soft and easily moulded to help them squeeze through the birth canal. Some skulls accept the deformation (compliance) and allow an easy delivery, while others. Its very common for a newborns head to have an odd shape.
“During vaginal delivery, the fetal brain shape undergoes deformation to varying degrees depending on the degree of overlap of the skull bones,” co-author Olivier Ami tells Medical Express. Fetal skull molding is no more visible in most newborns after birth. Two of the three infants with the greatest degree of fetal head molding were delivered by emergency C-section. And in five of the babies, their heads returned to their original shape after they were born. None of the babies had overlapping cranial bones in the womb, but the heads and brains of all seven babies changed to some degree during the second stage of labor. The transformation mirrored the shifting of fetal skull bones observed during the second phase of labor. In all of the babies, the fetal brain was observed to change in shape in the second stage of labor. The babys head may appear to be misshapen or asymmetrical. The researchers used 3D MRI scans of seven infants to compare the fetal head before labor and during the second stage of labor. Deformational Plagiocephaly is an abnormal shape of a babys head caused by external forces. Scientists have shared 3D images showing the process of fetal head molding, which is how the head of a baby physically changes shape to make it easier to move down the birth canal during delivery. A parent may first describe it only as a weird head shape, but a surgeon experienced in craniofacial abnormalities will recognize the misshapen head as a. The fetal brain changed in shape in the second stage of labor, and mirrored the shifting of fetal skull bones observed during the second phase of labor.

Caput and/or cranial moulding after a vaginal birth, a babys head is usually quite pointed as the part that has come through the birth canal first may be.
