A device for correcting the shape of an infants abnormally-shaped cranium by applying external forces over time with the growth of an infant to achieve normal shaping of the infants head. The device applies inwardly-directed external forces only to areas of bony prominence and minimizes (or altogether eliminates) these forces on the areas of the skull that are less prominent (or flattened). Because the present invention is non-conforming to the shape of an abnormal skull, the exerted forces cause accelerated expansion of the skull in less prominent (flattened) areas coincident with brain and skull growth. This causes the cranium to return to a normal symmetric cranial shape. The material that contacts the infants cranium is semi-rigid, relatively non-flexible, and maintains its overall shape under stress. For an infant with an already normally-shaped cranium, the device causes the infants cranium to grow evenly and maintain its normal shape, and thus prevents abnormal cranial shaping.
