for the last 2-3 days, my son (23 months old) has had a runny/stuffy nose with a slight cough at night. today his cough has gotten extremely worse, he's not weezing or anything, but just miserable so i gave him some tylenol (which he was gagging on), not even 5 minutes after he started coughing really bad and threw up everything. should i give him more or not? Also, my sister was diagnosed with bronchitis about 8 days ago and on antibiotics and an inhaler for it. do you think it could be the start of bronchitis??
