I would probably bring the df forward a bit to 10.30 if she is wakign for it
& I have to say WOW you have almost the perfect routine... If your lo is going to bed at 8 doing a df & going to 6.45am & the naps are like they are you have it going better than most people would hope for you have don't remarkably well.
You might like your lo to sleep past 6.45am, but hun, I'm afraid you have to accept one or 2 not quiet perfect parts of a babies routine, esp if you get good 1.5-2hour day naps
