Hi, I didn't have a huge problem since we trained her from NB. My mother in law taught me and it took me a few mths to work and plus my own method.
She sleeps on the mattress placed on the floor. In the evening, I will touch her head and sing 'head and shoulders knees and toes", all the way touch her from head to toe. very quick one. this i caught her attention and understand this is bed time.
I lie beside her, hum a slow lullaby once or twice. then i remain quiet. i wont be pulling her back. my girl the more attention you give her before sleeping, the more ATTENtive she is. if she trys to get up and climb somewhere, i tell her 'dark dark '.. she now understand dark is a little scary. within 30 mins, she will tone down to sleeping mood. just before she goes into deep sleep, i kiss her good night and tell her good night. then i leave the room. depending on how sticky your girl is, my girl will watch me go out but she has swicthed to sleeping mood. so will go to sleep ... hope this helps.
