Surprisingly, studies have revealed that the baby is the most common sleeping position. And perhaps not so surprisingly, this is mainly due to the position offering people a sense of safety while they drift off to sleep. An interesting fact about the fetal style is that far more women adopt it than men. More than twice as many, to be a little more precise.
The general consensus among therapists and sleep experts is that those who favor the baby sleeping position are very sensitive beings who present as being stronger than they really are in their normal lives. They can often be a little shy but usually have compelling personalities and tend to have a lot of friends. We really can't blame anyone for wanting to curl up so tight at night - the world is not always an easy place to be, so do whatever makes you feel good.
