DS went from crib-my bed to his own bed in his own room at 6m old. I slept in DS's room for 4 months after that and he was in with me for three of those months for most of the night. Once he started refusing to co-sleep then he was on his own. I wanted my comfy bed back!

Now I sometimes hop into his bed for a couple of hours (with cramped legs!) or he comes in with us. And half the time he's in with us DH moves to the sofa.

Things that helped with the move were not looking back - ie we allowed DS to come to our room but it was no longer "his" room. We let him play in his cot in the day in his room to create good memories - and a lot of toys are there as well as the piano; he loves playing with both and runs in and out of that room a lot. I used to snuggle in his cotbed and read him his story before climbing out so he'd go to sleep. He has NEVER been belittled for not sleeping or needing me with him. He's confident enough that he doesn't need it so much now - but I always reassure him that I'm always there for him, even when he can't see me. When he's asleep I love him, when he's awake I love him.

Monitors are always a good idea - I wake up the second DS does but not everyone does. I use one at my mum's house because it's so big I can't hear him straight away.

Write down what you do at bedtime. I bet you have a loose routine that you can tighten up a bit if needed for bedtime.

Best of luck.
