Hi, that sounds like she s ready for the transition.
I would try to put her at 11 for her first nap, but would let her sleep as much as she needs to since it will be her only nap.
And then we ll see from there. And remember as pp said the key to 2-1 is early bedtime, somewhere between 630 and 730.
If you feel that ur lo is tired in the afternoon, you can always try and put her down in her cot for relaxing time, ud be surprised how well it works!
We r still one 2 naps here, but lately lo skips her 2nd one, by playing in her cot for 45mins, in a dark room. When I pick her up, she seems to be very fine for the rest of the day, which amazes me.
Not sure if ur lo will like that, but you could try...
HTH hugs
