At that age, our mornings including two puffs of albuterol, 15-20 minutes of nebulized pulmozyme, and 20-25 minutes of CPT (6 positions, 20 spots to pound for a minute each.) In the evenings, it was a repeat of the albuterol and CPT. (As a side note, our clinic said we only had to do CPT once, but EVERYONE else I've heard from does it twice, so we do it twice too... I'd rather do it too much than too little.) When he's sick or has a runny nose or small cough we do this 3 times a day.
He was on enzymes, CF vitamins, D-vi-sol (vitamin D since he was breastfed), reflux medicine (zantec and prevacid... although now these aren't working at 15-months-old, so we're trying to find something new), Miralax (he had obstruction problems otherwise).
Now, at 15-months-old, he's on a lot more calorie supplements and an appetite stimulant. (He won't swallow any solid foods outside of his enzymes and a touch of puree mixed with a little bit of crushed crackers.) So, his bottles are made up of a mix of pediasure peptide, half-and-half, whole milk, MCT oil, and duocal. (If you're having problems with weight gain now, you can also ask about adding duocal to his bottles, and you can test MCT oil, although you have to be careful of allergies since it's created from coconut oil.)
