Preventing her from playing in the dirt would not prevent pseudomonas. You wouldn't want her to be in a bubble her whole life either. The best things you can do for your daughter is to be completely compliant with meds/CPT, practice good hygiene and be sure she gets plenty of exercise.
Pseudomonas does tend to recur, but it is not a death sentence. I've had pseudomonas for 17 years, and for 9 of them I needed no hospitalizations whatsoever. For the last 8 years, I have been hospitalized only once a year other than the year I was pregnant with Alex. I currently am on antibiotics, but in May my FEV1 was at 80%. Obviously every person is unique, but you will meet many people on this site who have pseudomonas and are older.
