My daughter has plagiocephaly and she will be 6 in March. We did go to a doctor and he recommeneded a helmet but said that her case was severe enough that even the helmet would not normalize the head completely. And her insurence didn't cover it.So we opted to not proceed with the helmet. She has since grown hair and while I notice it most others don't. It does sometimes make doing her hair a little more difficult but for the most part it's just a fact for us. Her plagiocephaly was caused by her being born with a nystagmus that she would turn her head to the left to dampen so she could see better. The head does continue to grow and may lose some of the flat as your child grows. The other posts have more info than I do and I found it interesting to read the different treatments. I think my daughter is now too old to have it treated.
