So, we were sent home with a nebulizer and are giving him treatments every 6 hours. They had us bring him in this morning for another listen to his lungs and they are sounding good with the medication, so this is what we will continue for the time being. He goes back on Wednesday morning for another check.
The unofficial diagnosis is that he has bronchiolitis brought on by RSV. The RSV test came back negative, but they feel the result was false since he is presenting as a typical case of RSV. Luckily it seems as if his Synagis injections are helping to fight it since he is not nearly as sick as he potentially could be. The nighttime is the hardest on him, so pray for sound sleep for all of our sakes!
