Well, don't feel to bad. I had it and I don't have ashtma. You may also want to get a humidifier, it really helps. I feel bad now, I know just how he feels, believe me it is not fun at all, but it does get better.
Ohh and I wanted to post this in the thread about getting dewitt to sign over his rights. Why don't you just go to court and file for sole custody. All you have to do is tell the judge that he never checks on or goes to see josh, and he doesn't provide support for him. That way the judge will most likely give you sole custody, so he can never just come and take josh when he wants to and, the judge will more than likely order him to pay support, and if he doesn't pay up, he'll go off to jail.
