Can my 6 month old baby get croup in the middle of summer?

Yes!: See pediatrician or pcp. I used steam vaporizer with my own children. Sometimes it worked.

Yes, but...: It's theoretically possible, especially if exposed to international travelers. But symptoms of croup during the "offseason" should prompt suspicion that your baby may have inhaled a foreign body.

Unusual: Croup is a common pediatric respiratory illness presenting in the fall and winter months. Most cases are caused by parainfluenza viruses.
