Self settling.

I can not get morgan to self settle. I'm pulling my hair out. I have tried everything that the other mums at mothers group have suggested and the child health nurses. At this current stage, instead of rocking I can get away with patting her till she goes off to sleep. But it takes me a good 2 - 3 goes of putting her into bed before she stays in there. Suggestions? She is happy to lay in cot for 10 minutes, and then goes straight to hysterical, there is no little cry in between.
