The night after my post above DS took more than two hours after a night feed and was still not settled so we wrapped him, a quick feed & straight to sleep. He sleeps better than ever now. I think he was giving us a clear message he was not ready to be unwrapped.

Next time we try I will try the one arm at a time technique...we might leave it a while though, we are all too traumatised & the pocket sheet is stopping him from rolling.
