Our three-year-old still co-sleeps with us. Is it time for her to sleep in another room?

We have the same problem! Our 3-year-old still co-sleeps too. Actually we too are trying to get him to sleep in his own bed. We even went out and got him a new bed. But, he won't hear of it. I think it is best to start early when it comes to getting kids to sleep in their own beds. The longer they co-sleep, the harder it is to get to be sleep independently. Have you tried rewarding them for sleeping in their own bed?
