Thanks everyone for their responses. I sent a list of questions taken from your suggestions to mom, including a list of all of his meds, a note from his doctor saying he is stable/healthy enough for daycare, an extended list of emergency contacts I can call if mom or dad can't get there fast enough, etc. I asked them to sign a consent form of what procedure I will follow should he have an attack or if he isn't breathing well, and a release of all liability. They said none of it will be a problem. IF I get everything I've asked for, I'll probably take him on starting at 3 days/week. We'll see how it goes. Thanks again!
