Looking at that I would suggest you are getting UT wake-ups at night, and possibly resistance at nap time for the sane reason. She really has quite a short day for a LO this age, most will be stretching out to a 12.5-13h day before transitioning to one nap so if you look at it that way you have an awful lot of daytime still to play with for fitting two naps in
Does the 9am start suit you (in which case I'd be looking at a 9-10pm bedtime) or would you rather start the day earlier and keep BT at around 8.30pm?
I'm going to assume the 8.30pm bedtime for now but please feel free to change it if something else would work better for you
My suggestion would be to wake her at 8am - 11-11.5h in bed is plenty. There's a danger being in bed for 12.5h overnight will rob her daytime sleep, even if the night is broken. Then I'd aim for something like this:
WU 8am
Nap 12-1.30/2 (in an ideal world)
Nap 5.30/6 for 30 mins (wake her)
BT 8.30pm
The reason I'm suggesting that is that currently she has one 4h A time, then around 2.5 and 3.5. Sometimes it's not just about total A time in the day, but getting it properly distributed so LO is tired enough from some longer stretches awake. You may run into issues with CN resistance, it's common at this age. You can AP the nap (car/stroller) or compensate with an early bedtime. If it starts being a consistent issue then the options are to get on with pushing the one nap late enough in the day to get you to a reasonable bedtime without massive OT, or switch the day around to give a morning catnap and longer pm sleep which should avoid pm nap resistance.
Thoughts??
