Why do babes rock back and fort when they are in their cribs?

Babies often rock back and forth in their cribs as a self-soothing mechanism. This rhythmic motion can help them feel more secure and relaxed, mimicking the sensations they experienced in the womb. Additionally, rocking may aid in their development of balance and coordination as they explore movement. It's a natural behavior that many infants exhibit while trying to fall asleep or calm down.
