Is he moving from a different room into this one or is he moving from your room into his own? When Nathan & Lydia had difficulty doing something I'd bring their toys & teddy's into the conversation, for example last night I'd have said 'teddy can't sleep 'cause you're still awake, or teddy can't sleep 'cause mummy is taking up all the room' you know that type of thing. I hope you have a better night tonight.
