Baby's Misshapen Head

After doing some research on the Internet, I've come to think my 3-
month old boy has plagiocephaly -- a mishapen head. It's subtle, but
his right forehead protrudes more than the left, his ears are not
lined up when viewed from above, and his head simply doesn't look
symmetrical, especially when I look at him in a mirror. Most of the
information I've come across advises against leaving him on his back
for too long, not leaving him in a car seat, providing plenty of tummy
time, altering his position in the crib, etc. But all the points of
advice are things we're already doing. I belive his misshaped noggin
is due to the fact that he had low amniotic fluid during the
pregnancy.

Which brings me to my question -- since we already routinely perform
the suggested "remedies," are there any other alternatives besides
head gear to try and bring his head to a "normal" shape? The thought
of my precious baby wearing round-the-clock head gear for six months
breaks my heart.
