Sometimes I think this is one of the harder aspects of dealing with CF. I Am still learning how to deal with the what-ifs. Time helps, watching my daughter 's personality develop into an out-going happy,well-adjusted child has helped me cope alot. My husband says Maggie has the right attitude. She does her"puff-puffs" and VEST, takes her enzymes and medicine and then every minute in between is filled with little kids stuff. I felt I am learning to deal with the what-ifs through Maggie's example. It is not easy though. We are older, have a better understanding of what can go wrong. I guess the thing to know is we can not control everything. I find having some time to burn off my anxiety, helps. Running is my medicine. Now that Maggie is older; we can have a babysitter. IT's ok to go out with friends for dinner. In fact, I KNOW my daughter would want me to go out and have fun. She'ld be angry with me if her CF kept our family from doing the "normal" things. Don't know if I'm ranting off topic but I've found this what-if thing to be a challenge for me personaly. HTH
