Our users share their knowledge on this topic:
- My 9-year-old son has Down syndrome; his speech is very delayed, but he uses sign language and facial expressions brilliantly. They have said he will one day have a full range of speech, but, at the end of the day - speech or no speech - these children/adults will always make an impact on all those who they meet.

Why was the term mongoloid used to refer to people with Down Syndrome?
People with Down syndrome all have similar facial features and can look like they have Asian ancestry. In the past, people thought that the different races had evolved by different amounts, with the European being the most evolved and the other races were all less intelligent or able. The faces of the Down syndrome people looked like the Mongols of Asia, who were considered very undeveloped and unintelligent. So people thought they were a throwback and called them Mongoloids, both as a reference to their appearance and their supposedly unevolved intelligence.

If two people with Down syndrome had a baby would it have Down syndrome too?
Yes two non-Down syndrome parents can have a Down syndrome child. This is the most common situation, mainly because very few Down syndrome affected people are parents. Few Down Syndrome affected people become parents, partly because of reduced fertility associated with the syndrome, partly because of an increased risk of passing on the syndrome (very roughly from 1 in 800 to 1 in 3), and partly because of societal restrictions. ___________ Also, the parent(s) who has 1 down syndrome gene will be passed onto the child
