Routines and real life?

I have a 14 month old and I am having a horrible time trying to get my daughter into a routine. I’ve gotten the advice of put her down for her nap at the same time everyday, but today for example yesterday she took a nap at 11. I tried to put her down at 11 today and instead she ran around till 12... any advice? I’m trying not to use the cry it out method.
