What happens if you put them in the room together after the routine and close the door and leave?
Do they cry for you or do they happily play together?
I have one of those doorknob covers (but at 22 months they still cant open doors anyway). Since a gate wont work, how bout closing the door?
My twins dont stay in their beds if I am in the room. But they dont really care if I leave. (ds2 may cry for just a few seconds to a minute the "but wait a minute I dont want a nap" cry. But not in a "get me now I need you" cry.)
Branwyn just says "night mommy".
