I believe that it might be because when you are a baby your mom and dad hold you and rock you back and forth when you cried. I don't believe that all people rock back and forth when they cry though.
Can be...I am crazy.
No, not necessarily. Rocking back and forth alone is not an indication of autism, neurotypical people can rock back and forth too! It can be a characteristic of autism known as 'stimming' which is repetitive self-stimulation, it's a means of controlling sensory input to reduce sensitivity to surrounding sensory input.
There are a few mental problems that can cause chronic rocking back and forth. One of the main ones is autism. Also sometimes severe stress, like a nervous breakdown. Rocking back and forth without any other symptoms (like stress or depression) is probably not a real medical condition.
Some movement is normal,

The boat will probably rock back and forth, and you don't want people to fly off deck.
because that baby could go to sleep
There is nothing to it! Just sit on it and rock back and forth!
The rhythm probably calms them.
Skittles!!

Both. Rock is a type of music. A rock is also a part of the sediment of the earth. The verb to rock means to sway back and forth.
