staying out of the hospital

so at this point, on like day 1,000,000 of isaac having breathing problems, i'm ready to give up.  this month has been particularly bad.  this past week has been the worst of the worst.  we've been to the doctor, to kid's care, had a chest x-ray at the hospital and talked to several doctors on the phone, and he's still wheezing.  as frustrated as i am, isaac is more frustrated.  today he was put on a higher dose of steroids and a z-pack after having a test for whooping cough.  the doctor we saw today called isaac a "fragile asthmatic".  a little discouraging.  i got to the point today where i felt like he would be better off in the hospital for a few days, that we he would get around-the-clock monitoring and have oxygen available.  but he's rallying a bit, so we are sleeping at home again, wondering the whole time if we might end up in the emergency room in the night.
