  1. More frequent flat heads with preemies
  2. More frequent flat heads with twins
  3. More frequent flat heads with infants with dark skins
  4. More frequent flat heads with infants with weak necks (muscles)

If vitamin D is indeed a factor, there will be an increased frequency with

  1. Latitude or countries with low vitamin D
  2. Spring births
  3. Urban births
  4. Closely spaced births
  5. Infants who are breastfed (without vitamin D supplements)
