On the 21st March we celebrate World Down’s Syndrome Day. The date signifies the 3rd copy of chromosome 21 that all people with Down’s syndrome have. The global Down’s syndrome community including the Down's Syndrome Association, uses the day to help spread awareness and information with the aim of giving society a better understanding of the condition, which is the most common form of learning disability. One way in which they do this is through the #lotsofsocks campaign.
