Ever wonder what children do all day who do not have a family to love them? Ever wonder what children do who do not have enough stimulation or attention?
They self-stimulate. A bunch of our kiddos have come home with self-stimulating behaviors. They rock, they bang their heads, they chew (not suck) on their hands, they pull out their hair, they pick that their skin. Why? Because if a baby's nervous system is not stimulated enough, they will die. Literally, roll over and just die. The smart ones figure out how to keep their nervous system alive by forcefully stimulating it, over and over again.
Here is a video of sweet little ones in an orphanage in Russia. Notice the self-stimulating behavior, they are crying out to be touched, loved, talked to, played with!
