From one mom to another - this is really a decision you have to look into your heart and soul and decide what is best for you and your family. I have three children. My oldest (Sean, 6) was diagnosed at the age of two. At the time, we already had my oldest daughter (Carolyn, 5) who was 8 months old at the time. Maybe because we had Carolyn before the diagnosis and already knew the joys of having more than one child - we eventually went ahead with our "original plan" of having three children. I won't kid you - it was a hard decision. We talked about all of our possibilities. We opted to have an amnio done - and I would have to say that was the longest weeks I have ever had to endure. I knew it would be hard - knowing that there was a possibility of having another child with CF - but it was really hard being pregnant (and all those hormones) and with all the "what ifs" going through my head. I worried "what if the baby had CF and made Sean worse." I also worried "what if the baby was really sick right from the beginning." I doubted myself and my decision at least a hundred times. However, in my heart, I knew that I wanted another child - no matter what. In my heart I knew that this was the right decision for our family - no matter what. Sean and Carolyn were the two best things that have ever happened to me and I didn't want to live my life with any regrets. I wanted my life to be completely full.
We were very lucky - Allison was declared completely healthy and CF free. I am so thankful to have her in my life and can't imagine my life without her. She adds a sense of normalacy to our life, as well as to Sean's life. It is hard to be "too special" when you are one of three children. She gives him another person to play with, to laugh with, to keep him company, and for him to love. I personally am so glad that I went ahead and continued my life (and my family's) with all of our original intentions.
I also know several families who did not think that having more children would be in their best interest. Only you can make that decision. I wish you well and hope that you find a decision that makes you happy and at peace. Good luck!!
