i have three sons, the two older, ty and jon do not have cf. the little one sam, 4 has cf. my pediatrician, who is also my best friend, is very cautious sbout sam. my whole family lives in florida. on the river, one on the beach, and on a lake. i think constantly about sam and pseudomonas in the water. but cepacea can live in the soil and pseudomonas can live in drain pipes and lots of other places. when i get really worried, i try and think about that. my ped. says that as long as sam is "healthy" and not coughing that she feels like it is ok for sam to play in the water. there is no way possible that i can keep sam out of the water when his two older brothers are swimming and jumping on to the lake. i do so want him to enjoy life, but if he contracted it and i could have prevented it i'd be devastated. he wont put his face intentionally under water all the time so, i can rest for a little while until he becomes more adventurous, but sam has been going to florida and swimming for 4 years and has been "fine"good luck and have a good time,juliet and the three muskateers<img src="i/expressions/face-icon-small-smile.gif" border="0">
