Here is yet another excerpt from the pamphlet "Back to Sleep, Questions and
Answers for Professionals on Infant Sleeping Position and SIDS"

"There is some suggestion that the incidence of babies developing a flat spot
on their occiputs may have increased since the incidence of prone sleeping
has decreased.  This is almaost always a benign condition, which will
disappear within several months after the baby has begun to sit up.  Flat
spots can be avoided by altering the supine head position.  Techniques for
accomplishing this include turning the head to one side  for a week or so and
then changing to the other, reversing the head-to-toe axis in the crib, and
changing the orientation of the baby to outside activity (eg., the door of
the room).  'Positional plagiocephaly' seldom, if ever, requires surgery and
is quite distinguishable from craniosynostosis."
