Does she need you for naps? Are you able to put her awake at nap time & leave or do you pat her then as well?
I would start tonight, at bedtime! When you go to put her down, give her some time to see if she will settle on her own. If she's just playing, rolling, calling out, fussing, leave her. If she is crying & it sounds like she REALLY needs you, then you go in & do pd.
Have you had a look at the pu/pd board? There is lots of good info there how to use it, etc... Then for every awakening at night, you have to do the same thing.
