A.T.
For us it was following the routine...snack, brush teeth, story, bed, sing song, rub back, Mommy sits for a bit then leaves. Our oldest did have issues and kept wanting to get out of bed. We finally had to put up a gate. She hated the gate so much she would stay in bed if we wouldn't put it up. We also sit in the upstairs tv room while the kids fall asleep to help them feel more secure. Both girls also want to hear the tv going to help them fall asleep.
I think you'll get pretty general responses unless there is a specific issue. If you don't get helpful answers maybe refine your question.....Good luck!!
