Thank you all for the replies. The funny thing here is that DD doesn't know it's happening, so it is truly just MY nerves! I think she will be delighted to find out that she is moving to first.
Geofizz, I think a transition plan is a great idea. The principal seems to think that introducing her to the teacher the day before will be enough of a plan. I disagree. What I originally asked for was a week of half day first grade (I know...I was pushing my luck!). My dad will be able to pick up DD for lunch--and he plans on doing that until she asks him not to. I think that's interesting that your DS did 2nd as a subject accel, but then they put him in 2nd full time this year. Do you think it will be an issue that he has already done the material? Or did I read that wrong?
rusticity, as a teacher I know that handwriting difficulties can be very problematic. Glad to hear she has gotten over that hump. In my school, the writing load does not increase all that much from first to second.
whatsnextmom, thanks for the perspective. I really had not considered skipping her after the year began, so when I hadn't heard anything from the principal, I thought it was dead in the water. I guess the mid-year skip is something that is fairly common? The principal wants us to decide when the transition will be. She seems to think that January will be good. I disagree. I want it done ASAP, so DD can begin adjusting.
DD REALLY does not fit in where she is. I know in my gut that this is the right decision. But it's soooo hard to stand behind that, especially when I consider all the things that could go wrong. Thanks, everyone. :)
