A head-positioning aid for treating or preventing plagiocephaly and torticollis is formed of a soft, compliant beanie-style cap. A soft and pliable deflector is attached to the beanie cap and extends downward from near the apex to near the lower edge of the cap. The cap is applied on an infants head in an orientation to place the deflector at any required position about the circumference of the head. The cap and deflector are united by themed indicia designed to bring family acceptance of the cap to promote acceptance and thereby support long term usage, as may be required.
