Just posted this to another mom with question titled "Get the kids out of my bed." my Mother-in-law told me that when my husband was about 4 and they wanted him out of their bed, they played "Squeeze-Play." Basically, when going to bed, Joe was in the middle between his mom and dad. They would squeeze a little bit closer to him each night and when he complained, they'd say "You're just becoming such a big boy. No room on my side to scoot over... No room on my side either ..... You're such a big boy now." Joe got so upset and frustrated that he went and slept in his own bed. I think it took a week or two to slowly and gradually scoot closer and closer.
