As long as we’re picking nits, it’s generally considered better to refer to a child with a medical condition as a child with a medical condition, with the emphasis on “child” rather than the condition. So it would be “a child with Down Syndrome’, as opposed to “a Down Syndrome child”.
Neither this word arrangement nor the possessive on the word “Down” are something anyone should get concerned about-nobody should be that over-sensitive, but it’s considered more polite to say it that way.
I wasn’t offended in any way. I, in fact, made my own error. Syndrome shouldn’t be capitalized.
“So it would be “a child with Down Syndrome’, as opposed to “a Down Syndrome child”.So it would be “a child with Down Syndrome’, as opposed to “a Down Syndrome child”.”
I’m aware of this because I have two autoimmune “diseases,” both which can be controlled. There are folks who have what I have who want it phrased exactly the way you say. There are others who object strenuously to it being called a “disease.” I don’t care. I have what I have.
I do, however, like to get the name right.
