I'm done. The shenigans of DD over the past three nights have officially broken me. She has always been a crap sleeper and I have co-slept/fed in an effort to get more sleep. It's mostly worked, but she is now waking up hourly from 10pm and running around at 2pm in the morning, waking the rest of the house.
So it's time to put my big girl pants on and night wean/enforce the sleep routine. Please tell me what worked for you. I am currently sleeping with her on a double mattress on the floor (next to her toddler bed - that is the next battle). Ideally I want to be back in my bed, with her sleeping through the night in her room.
