                          I spent some time yesterday with an 8 year old boy with Down Syndrome. He   kept making a clicking noise with his tongue- it looked like he was making it   when swallowing.  What are the Down Syndrome characteristics that would   contribute to this? I could find no information regarding tongue abnormalities and Down Syndrome.
