My mom watches my 6 month old son. recently she was diagnosed with croup. should i be worried and have my son checked out? he has a slight cough.

Yes: The viruses that can cause a "croup" infection are very contagious - especially to children.

Maybe: If your son is acting sick then he should be see. Watch http://www.Youtube.Com/watch?V=bf5sxehpgck to learn more about croup.

Odd diagnosis: Croup is a label applied to a symptomatic infection of the airway in kids 6 mo to 6 yrs of age with a specific pattern of symptoms.I have seen it as old as 8, but have never seen the term used for anyone older, particularly an adult. I wouldn't look to the kids slight cough any more than any other time.Monitor and call in to the doc if you are concerned.
