Maybe have a little chat next time prior to the hunt how you like to be when on stand... and that it's a more serious period for you because you look forward to it every year. Give her tips on how other deer hunters are when on stand. Don't be too upset about missing because it happens to everyone.

May want to take her to the range to get some practice in... even if it's a different gun, like a .22 or something. Make sure her gun is zeroed as well.

I'd also suggest taking a backpack with extra clothes, etc. It's always nice to have them if you need them.

Teach her to have fun and that it's more about the experience and enjoyment of the whole ordeal, not just the kill.
