We have done the same as others. You can tell people that they should be tested as to carrier status prior to having a baby, but that's about it. I guess I can look at it from both sides since I have been there. When my nephew was dx with CF, I was 23 years old. The internet was not what is now, and I truely was just not that informed. I knew that it meant that I could carry the gene since my sister carried it, but that was about as far as the thought went. I don't remember anyone saying 'You should be tested before having children.' When I married my husband at 26 years old, all I knew was that I COULD carry the gene and that there was noone in his family history with CF, so no big deal. Now looking back I realize how foolish that thought was because we didn't know CF was in our family either! What was I thinking?! I knew that there was a one in about 30 chance that my husband could carry the gene as well, but besides speaking it in conversation, I just never thought about being tested. Well, long story a bit shorter, I have two daughters who both have CF. Wow! What a shocker to me because it really never even crossed my mind. (And I happen to be a college graduate who runs a business with over 40 employees--so I really am not a dumb person but my brain wasn't working too good I guess at that time in my life) And as I said, with internet access, I know SO MUCH more than I did then! Had I had access to so much information, maybe I would had been more prepared. Who knows! But I do suggest to my younger, childless cousins, to get the test so there are no surprises.
