Alys's mum told Newsround: "She wore her badge with pride and showed off her odd socks to everyone who commented on them. Alys is a very determined girl, who thrives off attention and encouragement. We need to stop focusing on what she can't do and focus on what she CAN do!"Image source, Daniel BarkerImage caption, Egerton Primary School made this fantastic formation to raise awareness. Head teacher Ms Hooper told Newsround: "Everyone in Egerton came to school dressed in yellow and blue, with odd socks. In the afternoon, we gathered on the school field to make a giant 21 to mark WDSD. We've been learning about how Down's syndrome is caused by an extra chromosome on chromosome 21 so we thought this was a fun way to raise awareness of the condition! We tweeted an aerial photo and received global support including from Mark Jones, the creator of WDSD."More on this storyWhat is Down's syndrome?Published21 MarchMeet massive footie fans Dan and DJ.
