Lateral dominance is an important developmental stage that prepares a child for writing, reading, problem solving, creativity, critical thinking and reasoning. Bilateral integration is another important stage that helps build a stronger foundation for learning.
Bilateral integration is the ability for a child to use both sides of their body in a coordinated manner, allowing them to perform fine motor skills, gross motor tasks, walking, logical thinking, studying, and more. This is why you see a two-year-old frequently eating with both hands, scribbling with a crayon in either hand, pushing a wagon with both feet, and jumping off the playground with both feet.
