In my opinion I think that she should just tough it out. And I don't mean that in a mean way at all!! If you tell the teacher to treat her different than others, then it is going to be even more obvious that she isn't 'normal'. No one wants to feel like they have CF and have to be treated differently. Children think differently than adults do, and they aren't really meaning to laugh at her. Us CFer's just gotta be strong and tough it out. She'll be ok <img src="i/expressions/face-icon-small-smile.gif" border="0"> Plus, singing is a good way to clear the mucous out of her lungs anyways. Maybe have her do some hough-coughs before music class to clear her throat before hand? I hope I helped and I hope you don't take my opinion in a negative way! Good luck! xx.
