Crossing midline is a fundamental part of human movement that involves the ability to reach across the body's invisible line dividing it into left and right halves. This skill is crucial in performing various everyday tasks such as dressing, reaching for objects, and participating in activities that require coordination between both sides of the body. Children typically develop this skill during early childhood, and challenges in crossing midline can impact their motor skills, coordination, and cognitive development. When a child struggles with crossing midline, it can hinder their performance in school. This skill plays a crucial role in various activities, such as reading, writing, and physical education.
