People with Down syndrome have difficulty with language and talking.  Many kids want to interact and play with their friends, but don't know how, are afraid they won't be understood, or afraid they will be told "no, you can't play". Some kids with Down syndrome get overwhelmed when too many things are going on at the same time.

Yes. Just like everyone, people with Down syndrome have feelings. They can feel happy, silly, sad, sorry, or upset - just like you. People with Down syndrome enjoy friends and family and can be hurt when someone teases or makes fun of them - just like you.
