Why do babies find it easier to sleep when they are given a to and fro motion, like in a rocker chair?

Google the “fourth trimester”. The theory is that for the first three months after a baby is born their preferred environment is still the womb. Rocking motions mimic the same rocking motion of floating in the womb. Parents are also encouraged to “woosh” softly to mimic the sound of the mother’s blood flow in the womb. I think there are some other ones from what I recall from when my son was born.
