I've read some of your posts and I think it's commendable that you're putting such a strong effort in for your daughter, especially since I've also read posts about people complaining, rightfully so, about how they have to convince their family members just to be there for them when dealing with a flare.
However, your posts also remind me a lot of my mother who worries a lot about what I'm going through and comes up with many ideas to try. There's a certain amount under your control but it all depends on how your daughter responds to the treatment she's going through and this may not happen as soon as you'd like - I can attest to that. So definitely keep asking the doctor all the questions that you have but also try to be patient with the treatment. Also you might think that you're hiding your emotions from your daughter but children pick up on what their parents are feeling (just like a parent can sense a child's feelings without a word being said) so I hope that you're not stressing yourself out too much.
Also, I agree with the others that, apart from maybe causing some temporary irritation, a colonoscopy shouldn't push the disease to other parts. All the best with the prep and colonoscopy.
