okay, a couple things come to mind as i read your schedule...
- i think she's waking at 5ish cause she's had enough nighttime sleep. 10-11 hours is pretty typical by 11 months. HOWEVER, i think she could be extending IF she wasn't hungry. her last bottle is around 6ish - and i think by 5:30 she's just hungry again, and that's why you end up feeding her.
- 3 hrs awake time is probably too much in the morning. if you could cut it back to 2-2.5 hrs before her morning nap you might see improvement at the nursery (and you might not, but she's getting old enough that 45 minutes isn't the end of the world). also, moving her afternoon nap back to 2pm should help too. i think by 3pm she's just so tired she can't settle properly and that contributes to the short nap there.
- if you can move her dinner (teatime??) a little later, you can probably push that last bottle a little later.
you might also want to read this... it kind of applies here:
https://babywhispererforums.com/index.php/topic,46907.0.htmlwake to sleep is a method where you go in about an hour before the habitual waking occurs, and you just kind of stroke her cheek (or whatever) until she stirs. you do not want to fully wake her up. the idea is that you disturb her sleep cycle enough so that hopefully she will be in a deeper sleep at the habitual waking time & not wake up.
hope something in here helps you!
