My 5 month old is sick & I'm not sure what to do for him? Please help?

I'm really sorry about ur sick baby. Take him to the hospital so the Doctor can check if his chest is clear or not and then would give drugs to decongest it and see if there is more to it than just the cough and cold. I hope this doesn't turn out bad because i share ur pains. I no aw my baby felt when he had a bad cough and cold that he coughed continously for 5 mins, i was intently looking at the watch that day i remember, and when he finally stopped, he burst into a loud cry out of frustration and pain that i cried for him.
