ISB will celebrate World Down Syndrome Day on Friday, March 19. It’s a day where we all “Rock Our Socks” to raise awareness and acceptance. Everyone is invited to wear bright, colorful, mismatched socks. Why socks? They are the shape of chromosomes. Why is World Down Syndrome Day on March 21? Down Syndrome is Trisonomy 21. Check out this short video to learn more about World Down Syndrome Day.
