Mom to saydee, my husband mark first cultured pseudo pretty young, before the age of five and although not as young as your daughter, he has been living wiht it for over 20 years. It' comes and goes, and it varies as to how often. in 2002 he cultured it again for the first time in about 2 years, then he was good for about 8 months or so, and cultured it again mid and late 2003, again in 2004, about 3 times in 2004, and hasn't cultured it since January 2005. The only way he can tell he has it, is that he can notice a different taste in his mouth (I can smell it if I am really close to him sometimes, I'm use to it now after 6 years but I still think, "there's that sweet smell again") and he gets a little more congested. Usually a course of Cipro cleared it right up (oral cipro), but in 2004 he showed a slight resistance to it on a culture and sensitivity panel, so the doctor put him on TOBI and his next culture came back clean.
I can imagine this is difficult, as it seems this might be the first "CF BUG" she has cultured, but as another parent said, "it's not all downhill from here". As I said, my husband has cultured it on and off for over 20 years, and he's a pretty healthy guy. Hope all goes well for her next culture and it shows up clear.
