As babies grow and develop certain milestones are often celebrated, such as rolling, sitting, crawling, and walking. As a pediatric occupational therapist, one of the milestones I always celebrate might not be visible to the untrained eye. Crossing midline, defined as the ability to reach across the body’s invisible midline with your arms or legs to perform tasks on the opposite side of the body, is a required skill for many higher level coordination activities.
This skill typically develops around 18 months of age. Oftentimes when children are referred for occupational therapy due to poor fine motor skills, handwriting, or coordination, they are not crossing midline efficiently.
