A dynamic infant head support for preventing, or correcting, the abnormal shape of a head of an infant, and a method of using the support for treating deformational plagiocephaly. The support is an oval-shaped pillow, with a central opening to receive the head of the infant to be treated. Spaced barriers divide the interior of the pillow into a plurality of compartments. A ring-like manifold passes through the pillow and communicates with each compartment. A plurality of valves is operatively associated with the manifold one valve is located in each compartment. The valves allow fluid, such as pressurized air, in the manifold, to inflate individual compartments. The manifold is pressurized by a pump, at a remote location. A remote controller is connected to the valves by electrical leads for governing the sequence of operation of the valves, and regulating the duration of time that each valve is open.
