When DS was one we took the matress out of the cot and had him on the floor- that way when he woke up i could lay there with him all cosy and then extract myself from him. This worked well and it wasnt long before he was in a big boy bed.

He really didnt seem to like the confine of the cot once he has been co sleeping in bed for so long- so having an "open" bed seemed to work for him. And for safety we just had him on the floor so he couldnt fall out!

Good luck!!
