Our son was diagnosed 3 months ago. We ordered and got the vest after his first clinic appointment. He went from being tired a lot to running twice as far as he ever did. We also called him "the little dragon" since he was always breathing so hard while sleeping. Now he's as quiet as his brother. He has been on several antibiotics for colds, but in his daily life he just takes 2 puffs of the inhailed albuterol then does the vest for 1/2 hour. He does this two times a day. While on the vest he likes to watch netflix. They have unlimited online viewing for like $10 a month. We use it a lot. He always does the vest at 100%. I hope the treatements will help your son feel better each day. It has for ours.
