The flat head syndrome, also called positional plagiocephaly, is a condition when a newborn sleeps with their head turned to the same side for the first few months after birth. This results in a flat surface on one side or the rear of the head. A baby’s sleep posture is the most prevalent cause of a flattened head.
Because infants spend so much time laying on their backs, the head might flatten in one location. This occurs not just when they are sleeping but also while they are in baby car seats, carriages, and bouncy chairs. Moreover, premature babies have a higher chance of having a flat head syndrome since their skulls are softer than those normal infants’.
