without physically tying him to the bed or locking his bedroom door?
He has started coming into our bed as well during the night, but I think that is partially due to moving and partially due to him getting a bit cold at night. We now turn his little radiator on and he only wanders in once around 01:30. However, come 05:00 he's wide awake, climbs into our bed and wants to play. We've tried putting him back into his bad with very stern 'go back to sleep' or such but to no avail. DH is loosing his tempter and will be migrating to the sofa!
HELP!
