It depends on whether both you and your husband are carriers or only 1. If only one (and all gene possibilities tested), it is virtually impossible for any additionalchildren to have CF. If you are both CF carriers, it is 25% chance.
25% chance or one in four... Does your little girl have any symptons -- digestive or respiratory? You may want to follow up on genetic testing. DS didn't have a newborn screen; however, he DID pass his sweat test. Genetic testing showed CF. I also have a friend whose son was diagnosed via newborn screening, so they went back and tested their 3-year old, who'd never been sick though did have some digestive issues and found she had CF as well.

Oh Valerie, I'm so sorry. Sending you and your precious little boy hugs and prayers. Is he the only with CF? Please write if there is anything we can help.
Sorry this turned into a LONG reply...
You found a great resource by coming here with your questions! The genetics part was a bit new to my wife and I, so we were a little unclear how it works at first. Aboveallislove makes an important point...a CF diagnosis happens when (1) each parent has one or more CF-causing mutations and (2) your child gets one or more mutations from each one of you.
In our case, we learned about CF through the newborn screen. It picks up some common mutations but not all mutations. Our two sons have CF and have the same genetics...one common mutation and one rare mutation.
The newborn screen detected the more common mutation for our first son. He had a sweat test which showed a borderline result. Our CF center also did the full genetic test, which detected the rare mutation. The result is a CF diagnosis.
Our second son also had the common mutation detected in the newborn screen. His sweat test result was much lower than his brother and in the normal range, and we first thought he was only a carrier (only inherited one of the two mutations). The CF center also did full genetic testing for him, which shows he did inherit both mutations. The result for him is also a CF diagnosis.
Aboveallislove answered your question about the chance of CF for another child, but in addition I recommend doing the full genetic test for your little one so you have a more concrete yes or no answer for their diagnosis.
Hope that helps!

Thanx honey, Were doing ok, still trying to cope and get all the info we can. Yes out of all the kids hes the only one that has it, they did the sweat test on Carmilla, our 17th month old, and it cam back neg. so we didnt worry about Marshall, But they discovered the hydrops with him so went ahead and took him 6 weeks early. His intestines were twisted and he had to have surgry that night. So started doing the testing and discovered he had CF. Right now the cf is causing alot of probs with his healing and with his food.
