Rolling is one of baby’s first forms of mobility. It allows baby to start the process of seeing something and actually going to get and explore it. Rolling is a complicated movement that requires the two sides of the body to do opposite movements. This is important for the brain- body connection (i.e., how the body learns to respond appropriately when the brain says “reach”), to build neuronal maps (i.e., how baby will learn to move in 3D space), to strengthen bilateral coordination skills (i.e., to use both sides of the body), and is preparing baby to develop more complex movements.
