AndieE - We have exactly the same sleeping issues with Will. He slept in his cot in his own room from day 1 till 9 months all night (when I returned to part time work and sep anxiety started). Then he started waking all the time, so I just put him in bed with me to get some sleep myself. He also would only go to sleep hanging on to me. Now our scenario is he sleeps on a mattress on the floor next to my bed but goes to sleep on my bed and lie with him. Then I move him onto his mattress.

We have recently been discussing the moving him, not lying with him options but my heart just can't do it...so I think I will leave him because he sleeps nicely on the mattress now most of the time.

My issue is when bubs comes along and BFing overnight - it will wake him. So perhaps I will trial moving his mattress...all so confusing!

In my opinion - I think you have enough on your plate with bubs and this massive transition, so if you can stand it leave the sleeping arrangements until it has all settled. I don't know whether it is true, but a lot of people have warned me that toddler regresses when bubs comes along so it is probably not the time to be trying something new unless it is driving you crazy!! But just my thoughts .... and I am always wondering what to try!

Good luck with it!
