Crossing Midline Alphabet Sequencing for Children with Sensory Processing Disorders

6 years ago

Some children with Sensory Processing Disorders (SPD) avoid crossing midline. Imagine a line running down your body dividing it into right and left sides. This line is called “Midline”. Sometimes your right hand will cross over left of this line and your left hand will cross right of this line. We describe this as "crossing midline" (CML).

Children with SPD often avoid crossing midline. They may only reach for objects on their right with their right hand and only reach for objects on their left with their left hand. This is not very efficient, especially when they color with whichever hand is closest to the crayon rather than the dominant hand.
Activities such as the one in the video are designed to promote CML. Ask the child to alternate using right and left hands while sequencing the letters and at times they will need to cross midline.
