T.N.
My son is almost 3, and we try to make the bedtime routine nice and bonding so he gets his fill, but when we leave we say, "Would you like the door open or shut? You can have it open if you stay in your room." He usually says, "open" of course. And if he wants to play in there a little, there's not much we can do about it. We can't force him to fall asleep. BUT if he leaves the room and tries to come out (with a few exceptions like going potty) we say, "So sad. You chose to have to your door shut," and we gently lay him in his bed and shut the door. He knows that we follow through and so he rarely comes out. We have recently gotten a little lax about setting the limit and following through (because we hate to see him sad), and he works the system now. It gets so exhausting when he comes out over and over and we keep putting him back in his room and we never get alone time. So I think we'll reclaim our quiet evenings alone again for our own sanity. It's hard to never feel refreshed.
