Here's my 2 cents for what its worth.
Every kid is different, which I am acknowlegding, but my experience wasn't good with being given an escape clause for things.
The few times my mom got me out of things b/c of cf (when it really wasn't warranted), it did teach me that I could get my way out of something if I used it. My mom learned quickly that it was a mistake. It brought me alot of bad experiences. I really wish I had tried harder in school-that is a <i>huge</i> regret of mine. And you can't go back and do those years again. Then when job time rolled around-there were a few instances when I tried it with work related stuff. I learned fast that its not tolerated in the real world. I wasted some good opportunities b/c of it.
I think you should put your kid through regular kid stuff. Cf isn't a mental handicap. In fact-most cf kids are <i>smarter</i> than their peers.
Yeah, there are teachers that resent cf kids missing so much school b/c of hospitalizations-I had 2 teachers once that didn't like me b/c of it, and refused to work with my hospital tutor to keep my studies up while I was sick-thats a different situation though. The parent should get involved in that and go to the teacher or principal and work it out, or switch teachers is neccessary. But giving up at the first sign of trouble isn't a good lesson to teach your kid. They will face obstacles with college, careers, relationships their whole life. They cant run away each time or they won't get the most out of life.
Just my opinion.
