I'm posting here for as much insight as possible. I know there were a couple on this board who's blossom were diagnosed with it and had the helmet.
Today when I was walking with William in the ergo carrier I noticed it and later while giving him an olive oil treatment for cradle cap DH noticed it. It seems to be on the right side, and I haven't noticed Torticollis (one reason for Plagiocephaly) I'll be more aware now and look for it. I do know that William sleeps alot more than Aidan ever did, and I'm not as anal about repositioning him each time he nurses at night or when he naps.
Anyway, here's a pic I took today of his greasy crooked noggin LOL. any insight would be helpful
