K.H.
Do you want her to go to bed earlier? Is this why you want to change the routine? I think that her being awake still at 11pm is too late , she is so little and needs her sleep , but the problem you have is that her 2nd nap is too late BUT she still needs a 2nd nap , so here is what I would do , wake her up earlier in the morning (yes she is going to be tired still because of going to bed so late) , I would wake her around 7.30 , that way she will be tired and wanting a nap around 9.30/10 , then her second nap will happen around 1pm for 2-3 hrs , then she will be sleepy come 7pm and ready for bed around 7/7.30pm. Her eating schedule seems fine , you would just need to move the times to fit her new sleep pattern.
Hope this helps
Just wanted to add that if you take the time to read her post correctly , she says pretty clearly that her daughter takes 6-8oz every 3 hrs , and she also states she has 2 naps!
