I can relate. You described my son. My son does well in his subjects and has issues with writing and tying his shoes. I did research and found information at Understood.org. Definitely check out Dsypraxia or DCD on that site. It was my aha moment with my son. It is typically associated with kids with ADHD. My son doesn’t ride a bike and couldn’t tie his shoes correctly. His handwriting was also horrible. I worked with his psychologist to get him referred for both Occupational and Physical Therapy. The visits help. I wished I had did it sooner.
