Positional plagiocephaly is the most common form of plagiocephaly. It occurs when a baby's head develops a flat spot due to pressure on that area. Babies are vulnerable because their skull is soft and pliable when they're born. Positional plagiocephaly typically develops after birth when babies spend time in a position that puts pressure on one part of the skull, such as the spot where their head presses against the mattress.
