According to the Royal Children’s Hospital in Melbourne Flat Head Syndrome is the most common craniofacial problem today, and literally means a misshapen or asymmetrical head shape. This condition most commonly occurs when baby adopts a favoured head position, and as a result the sides or back of the skull become mis-shapen from constant pressure in that one spot.
In the first six weeks after birth, it is not uncommon for baby’s head to appear slightly out of shape from the pressures of birth. This usually resolves by 6 weeks of age. However, because an infant’s skull is soft and malleable, deformities in shape can occur if baby begins to favour certain head positions.
