Now we've gone and moved on him so we're back to square one but I will get there....
Funny you should mention that. I went on holiday 2 months at parents and first month was co-sleeping. came back, spent 2 nights in old house fine but then moved and she was back co sleeping until we (gently) relaxed her back.

I layed next to her cot with my hand in it until she dozed then dozed myself on the floor to reassure her i was still there. I dozed next to her cot and put my hand up everytime she woke to grab her hand.
