Your day yesterday looks almost the same as ours, although x napped 12-1.30. His nw was at 11.30, went straight back to sleep once I went in and laid down on the mattress and then he woke at about 5.45 this morning. I have to say that I would be happy with that day (minus the nw) so I am trying to recreate it!
How consistent is she? If she will do exactly the same day for 3 days, then I think you should try that then push her nap by 15 minutes and bt as well for 3 days, then push again to see if that can shift her day. It doesn't work with x because he doesn't do the same thing 2 days running, but if m will then that might be your best bet for moving bt.
