DD is 3.5. We moved her out of a crib last fall, and dropped the pacifier right after her third birthday, both with little fanfare. Over the winter sometime, the bad habit of laying down with her while she fell asleep crept up on us. The current bedtime routine is brushing teeth, using the toilet, changing into pajamas, reading two books, one story/chat with each parent who is home (usually both of us, but sometimes only one), and then whoever went second telling a story lays down with her until she falls asleep. Some nights she passes out fairly quickly, but other times it seems to take FOREVER for her to fall asleep, and the parent's presence is clearly a stimulation/distraction.

I am so ready to drop the cuddling-to-sleep, but I am not sure which strategy to use. I know that I have to start being firmer about obvious stalling techniques (I have definitely been letting some things slide for the sake of not escalating late at night, but I am now on summer break and ready to dig in), but I don't know whether to go with bribery, gradual change, cold turkey, etc.

If you have weaned your preschooler off of having a parent in the room until they fall asleep, what worked for you?
