I completely understand about the issue with being little and lungs going through alot of the development issues, then on top of that dealing with CF. I didn't know he had CF for 10 months, he went through lots, lots of testing for all types of things before I asked for the CF test. So I really didn't know what I was dealing with. In my situation, (I am the mom to the 3 1/2 yr old w/cf), I haven't really had a choice about having to work. I have to work due to needing the 2nd income as well as I am the holder of the insurance. So, in a way the decision was made for us regarding having to put him into a daycare setting.
My employer has been absolutely wonderful regarding my time that I have needed to take off for hospital stays, (which were quite a bit right after his diagnosis at 10 months), clinic visits, going to daycare to administer the IV meds, etc. I also have FMLA for all of this as well though, so they really aren't given an option about being understanding in some respects.
In looking back, I'm glad to have not had to make the choice, but do think that it has been good for both him and I to have me work. It allows me the break (sad as it's usually my only time away from him) from "CF" for a part of everyday and him a break from his crazy mom! I know that he enjoys the day with the other kids. Germs they are everywhere, while I don't promote contact with them, I do not try to limit his activities too much.
