My baby is 9 months, and he wore a helmet for about 15 weeks. I'm a perpetual lurker, not a poster, but I just had to respond to those who are dismissing Meghan's decision to put her baby in a helmet.
I apologize in advance that I cannot quote people directly, as I am not sure how to work that function. My baby had plagiocephaly secondary to torticollis. His need for a helmet was not purely cosmetic. Flat heads can lead to vision impairment, hearing problems, and TMD, among other issues. My baby's cognitive function was never at risk; however, the brain cannot grow fully and properly if a baby has a severe flatness to their heads. Helmets are necessary to retrain the growth pattern of the baby's skull while the bones are still very malleable. Early intervention allowed for a very short treatment time and increased compliance. Waiting or ignoring this as just something that happens to some babies makes treatment more difficult.
If the poster (Mu Shu) who commented about having the mind of a scientist, despite having a flat head, was an actual scientist, you would know that science is about advancement in technology, understanding why conditions occur, and what we can do to prevent conditions from having long term consequences. Yes, it is serious, and dismissing Meghan and others for doing the right thing for their baby's health and well-being is the wrong attitude.
What I've learned while going through this with my son is that I too have torticollis, which could have been treated when I was a baby, and that asymmetries in musculature and posture begins at birth and can be prevented.
I had to answer a lot of questions about why my baby needed a helmet, but I was happy to do so to educate people so that the stigma of wearing a helmet is diminished. Besides, he looked so dang cute in his Snoopy helmet!
And I'll add, there are other, more serious, reasons some babies may need to wear a helmet. The one that comes to mind is cransynostosis, which is a very serious and debilitating physical issue. So, please, don't dismiss what Meghan is doing. She's doing what is best for her baby, and should be applauded for it.
