I've read it and LOVED it. My little one with CF is only 18 months, but I was able to quickly apply some of the parenting methods to my 3 year-old and the results were AMAZING. You have to retrain yourself some, but I'm sold on it. It is well-written, great ancedotes, and easily applicable solutions. I've referred several parents to the book who don't have kids with CF, but autoimmune disorders and lupus.
PM me if you have any questions. You can also PM LisaGreene if you have any questions as well. She's great.
