Hi,I am the mother of two children. I have a four and a half year-old daugter and a 19 month old son who was just diagnosed with cf. I took him in for his 18 month check-up and the PA started asking me about his stools, history of wheezing when he gets a cold and his growth. He is small, 21 lbs, but he has been growing steadily. We took him in for a sweat test which came back at 92. Needless to say we are crushed. I have never even known someone with cf. I am scared, depressed and so worried. If anyone out there has some advice I would really appreciate it.Thanks!!!!!!!
