Positional plagiocephaly is cranial asymmetry caused by prolonged pressure on one side of the skull. A child with this diagnosis may require helmet therapy, where a custom-made helmet is worn up to 23 hours per day for ~ 3 months.
Educate caregivers to perform 10-15 minutes of "tummy time" ≥ to 3 times daily for all infants, and alternate head position when placing the infant supine to sleep.
