I recently read an article about positional plagiocephaly.  What is this, you may ask?  Well, positional plagiocephaly is when a baby's head becomes misshapen due to constant pressure on one part of the baby's soft skull.  This pressure causes the forehead, ear and sometimes the cheek on that side of the head to push forward and leave a flat spot in the back.

This problem has grown since 1992, when health care agencies first began the "back to sleep" campaign, advising parents to make sure babies slept on their backs.  Unfortunately, some babies spend too much time on their backs, in bouncy chairs, and car seats, and on the floor playing.  And this may cause the pressure that can change the shape of a head.

Positional plagiocephaly is not thought to cause mental retardation or developmental delay, and it may be corrected by something as simple as alternating the baby's sleeping position.  More severe cases can be treated by  wearing a helmet that uses pressure to push the skull bones back into place. 

So to keep up with all the new information, we now need to think:

Back to Sleep, Front to Play

That is, until we're told differently in another few years.

I'm sure there are others, but this one has pretty basic information.
