Lots of good advice! Here's my two cents:
I would recommend first making sure there aren't allergy or sinus issues disrupting her sleep.
Then, an earlier bedtime. The CDC recommends between 13-15 hours of sleep for children ages 12-18 months. It seems counterintuitive, but it was our son's problem. He sleeps from 7:30pm-7am now. http://www.cdc.gov/Features/Sleep/
He also tosses and turns, moans, talks, and sometimes even laughs in his sleep! We have had to learn to partially close the door in his room and our room so that we sleep thru his "normal" sounds. When he needs us he cries louder or calls for us. It was really hard for me at first but then we started to see the rewards of good sleep all around - we were all happier and functioning better after just a week!
Routines are also very important. We started with reading a book downstairs then telling him, "lets go brush our teeth" and taking him upstairs. Then we'd change him, give him his bottle, say a little prayer and cuddle - putting him down while he was still just drowsy. It took some work, but we're all doing really well now with him sleeping thru the night unless he's sick or something else is bothering him. (if something random like gas or growing pains we use a couple doses of Hyland's Colic Tabs)
When he was about 13 months we did get him an alarm clock from Target that makes ocean wave sounds. We moved from the city and there wasn't enough noise - that's how we coped at first, now he's fine and enjoys hearing the train whistles as he drifts off.
Letting her sleep in your bed is just a slippery slope though - and no one gets the sleep they need! Believe me, it took 2 weeks of him crying himself to sleep to break that little mistake! Oops. None worse for the wear though!
Hope all this helps you and you ALL find some well deserved sleep soon!
