My Son is Sick Again...

I'm hoping its not pneumonia, but it may very well be. He has these coughing attacks that keep us all up during the night. He is a very thin boy and tends to run on the sickly side of the line anyway. I'm praying that he will be healed. I will be taking him to the doctor to see if it requires medications or just the breathing treatments I have been doing. The saline solution by itself can't really be helping that much, can they?
