My almost 5 month old is congested, stuffy nose and I can hear a rattling in his chest. He has no fever. But we are getting on a flight to California on Sunday from NYC and I need to know if we can fly - and if anyone has had experience with Vicks baby vaporub?? We have been giving him Tylenol, steam showers and a humidifier as well as the nose Friday every few hours with saline.
