My school does the same. One big ceremony in June (I think) and I graduate in August. I can walk in June, but it seems dumb to me since I won't be done. I have already walked for my other degrees and I'm really just looking forward to pinning. I would possibly go to graduation if it was when we graduated, but oh well. I can understand how that's upsetting for you though. Can you do a pinning ceremony for your class? Each of our classes gets one when we finish (trimesters) then there's the one graduation. I also don't think it would be too crazy to walk next year. You will still have earned it and your daughter could still see it all happen.
