Am at my wits end with DS. Until we moved him into his own room, he slept fine in his cot. Now, he hates it with a passion, and no matter how asleep I think he is when I put him in it, he rolls straight over and is wide awake and standing up, screaming if nobody is in the room/takes him out of the cot quickly.
We've tried everything we can think of. PUPD, gradual withdrawal, I even slept on his bedroom floor for a week, but it made no difference. Even if I could get him down, as soon as he was disurbed by a noise/breeze/whatever, he'd be up and howling.
The past two weeks me and DP have been taking it in turns to share the bed with him while the other goes on the sofa, and it just isn't viable anymore. When he's with DP it's alright, but I fidget a lot in my sleep, which wakes DS up, which makes him grumpy and more likely to move around, which results in him falling off the bed 
So I have to stay half-awake to stop him falling off, and I can't sleep properly on the sofa. I'm functioning on less than two hours sleep a night most nights, and I just can't keep doing it when I have to look after DS on my own every day. I'm losing the will to live, and the energy to do anything but the most basic tasks.
We've thought hard about it and are going to try CC when/if DS ever decides to go to sleep. I know it's going to be awful, his crying goes right through me, but I don't see any other solution.
Would appreciate any hand-holding/advice.
