Hi everybody! I've been rolling my head to fall asleep it from the crib right up to today.
When I was still a baby, my mother used to be very anxious about me doing it, fearing some obscure neurological condition, so she consulted with several pediatricians. As it was obviously too soon for me to confirm that the head-rolling was voluntary, some doctors suggested invasive pharmaceutical treatment. She finally consulted a sleep specialist that went to this admirably simple workflow with her:
1. Does it help him sleep? (yes)
2. Does he seem to enjoy it? (yes)
The clever doc said something like: “Well, then, let the poor child be, for God's sake”, so my mom chilled out about it, and I turned out perfectly fine. I'm a 24-year-old male with good social skills (no autistic/Asperger-like condition). Throughout my teenage years, I had to learn to fall asleep without doing it (e.g. when I had friends over at home, or when I started having a girlfriend), but I still enjoy doing it when I'm alone. It makes me feel the "rollercoaster" effect other people in this thread have mentioned, helps me let go of uneasy thoughts and fall asleep quickly. I rarely "stop" doing it voluntarily, rather falling asleep directly in the process.
Moral of the story: people have some very unique habits and pretty much anybody does something special that people are quick to diagnose as a super obscure neuro-mental-social-linguistico-autistic condition, but this particular thing is probably a remnant of the soothing movements from your time in the womb, when every micro-movement of your mom would “rock” you in the amniotic fluid. It is also the reason why the head-rolling is so common in babies at the age where they are forced to figure out techniques for falling asleep without their mom's help.
Why shouldn't people be allowed to rock themselves to sleep once in a while?
