DS has two copies of the delta f508 -- homozygous.
A friend of mine, whose granddaughter wasn't diagnosed until she was 1 1/2 struggled with CPT also. They were able to get the vest shortly afterward when a bronchoscopy showed issues with inflammation. DS tended to give us issues with his CPT, when he was 1 1/2 to 2 -- mainly during the mid-afternoon treatment because he wanted to go play -- he'd block us with his arms and yell owie. And sometimes his back would be easier, so we'd give extra attention to the spots with the least resistance, knowing that things would most likely be easier for the other cpt times --slept thru the morning one and would fall asleep during the evening one.
