Dd slept in a cot still at 1 year, BUT once I let her sleep in her "big" bed her sleep improved dramaticly yay!! Try the big bed... just make sure that you place a mattress on the floor so that if he falls off, he does not get hurt. Dd fell out of bed three times and that was it. She still needs the mattress to climb onto the bed (she pulls it out from under the bed herself) but she can get off now without hurting her and I too love that she comes into our room at night to get into bed for cuddles ...
