I'mwondering if any of you notice that you or your children WOCF show any symptoms? I know they say that you either have cf or you don't but I notice that myseof and my sons have just some of the symptoms but don't have cf. One son has gi problems, and doesn't eat, the other son had asthma when he was younger and all his cold go into his chest. I myself have problems with asthma and reflux.
