Hello, my 6 month old (4 month corrected age) has croup since Monday, his temperature has dropped to 34.7 degrees tonight, I used a digital thermometer under his arm. He is also sweating. Still has a Barky cough and noisey breathing at night. He sleeps in a room with a vaporiser, will this help with his croup? Should I be concerned about his cold body temperature while he is sweating?
