DD (almost 4) and DS (19 months) are desperate to sleep in the same bed. I'd love to encourage this -great for their relationship and super cute, but we've had a couple of trial runs with naps and it's left me unsure.

After some opinions:

- how old do you think the youngest has to be to cosleep unsupervised? He's a pretty robust little guy, but I still wonder about risks to him if DD is sleeping heavily. They'd be in a king single mattress on the floor.

- if your kids co sleep or room share, how the heck to you get them to stop playing and actually go to sleep??!
