I don't know what the Scandi Shakes are, but I have read other posts that mentioned them. We have tried the Pediasure and Boost type drinks, but the problem is she doesn't like them. In fact she is a very picky eater, doesn't like ice cream or shakes or sweets in general. If she would eat enough I think she would gain, but she has a very poor appetite. Vivian is a cutie!!! Is she doing okay? I'm sure you have heard about the Derby that is coming up tomorrow, have you picked a horse? Mine is Dominican, a long shot but has local ties. He was named for the dominican nuns at the college I am going to (St. Catharine) Yes I am a 35 year old college student. He is from the Silver Hill Farm about 30 minutes from where I live. Samantha's CF is very mild, she has mostly digestive issues, very few lung issues. I guess we have been fortunate this far as she has never been seriously ill. Has Vivian had many serious illnesses? The more I read about CF the more I realize that no two CFers are alike. I just wish I knew what the future holds. Take care.
