I sort of did with DD when she was around 8 months old, but soon gave it up as a bad joke. She always was a good sleeper though, would often just lay down after a bed-time story, snuggle up to her teddy and off to sleep.

So far with DS, I'm just following his lead. He feeds to sleep most of the time, but every so often he'll push me away and look at his cot. So I put him down, and he'll chatter/grumble to himself for a bit then nod off. I'm not messing with it, we're onto a good thing.

I don't want bed-time to be a stressful, negative experience. Cuddles, bed-time stories and wind down talking about our day all make going to bed a restful, relaxing time.
