because that baby could go to sleep
You can rock the baby to sleep or sing to the baby or sway back and forth.. be creative!
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.
Rocking chairs are an ideal way to rock a baby to sleep. The closeness of being held and the repetitive back and forth motion soothes the baby and relaxes the mother too.
Rock to sleep is a term used when you are holding someone or something in your arms and swaying it back and forth gently till it falls to sleep. For example you could rock a baby to sleep in your arms or a small animal/pet.
The toilet may rock back and forth due to an uneven or unstable floor, loose bolts securing the toilet to the floor, or a worn-out wax ring seal.
One way would be to hold the baby in your arms and rock them gently back & forth. Another way would be to wrap them in a blanket and pat their back gently. You could also check if they need to be changed or fed.

The rhythm probably calms them.
There is nothing to it! Just sit on it and rock back and forth!
Yes, the particles in a rock do vibrate back and forth, but the movement is very small and not easily detectable without special equipment. This vibration is a result of the thermal energy present in the rock causing the particles to jiggle in place.

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.
