We had my daughter's first official visit at Riley's CF Center yesterday. The RT wants us to start CPT and then think about the vest in 6 months or so. She is almost 3 and does not have any respiratory symptoms, but obviously we want to keep it that way. She is very interested in the percussing and likes it for ABOUT 5 MINUTES! Then she says "I'm done," and runs away to play. Obviously it is not effective if I am chasing her around. yesterday i got maybe 10 minutes in. How the heck to you make a 3 year old hold still for 30 minutes of percussing???? I am very anxious to get the vest instead as that seems like it would be a lot easier............
