I had so much trouble with DD2 (who's now 3) and her sleeping, as it seemed the only place she wanted to sleep was in the big bed, and she too would wake up multiple times during the night.
Once she was about 14-15 months I moved her into her own bed, and I found then it was quite easy to establish a routine for bedtime, one we stick to to this day. Ive also found that if she feels the need to get up during the night (which she still does) she is able to get out of bed and come for us, as opposed to feeling trapped in by her cot, which I think added to her distress.
We have dinner, bath, quiet time with a bit of TV, say good night to everyone, tuck into bed, read a story then say good night with light left on, once shes asleep I turn it off. In the beginning too I played some nice gentle music and stayed in the room until she drifted off...no talking and no making eye contact, just being a presence in her room so she knows shes not alone.
I would also recommend using Brauers Calm solution too, just at bedtime, to help you establish a routine...this is readily available from the chemist and is a homeopathic remedy. It can also be administered 4 hourly during the night so if she wakes up you can give her some of that and help her settle again.
