2) Uterine Constraint (limited space in the womb)
Limited space in the womb (e.g., multiple births, breech position, small pelvis) can cause head flattening before birth.
3) Lying for long periods of time
Lying too long with the baby’s head in one position in car seats, strollers, or bouncers and bed because the bones of a newborn baby's head are thin and flexible so the head is soft and may change shape easily.
4) Positioning during birth
A baby’s head may change shape during labour due to pressure; this could be caused by the
size of the birth canal, or instruments used during delivery.
5) Premature babies
Premature babies have flattened heads because their skulls are less developed. They also
spend more time lying down in the hospital and in the Neonatal Intensive Care Unit (NICU).
