hmmm... umm.. trying to think what I do! LOL. I wrap him in bed, but I tend to feed him to sleep most of the time. Once he's asleep and I put him in bed, he starts to squirm and carry on if he wants to be unwrapped. So it's kinda in his sleep that he's doing it. So I release his arms, and he sleeps. He does usually stay wrapped for that first part of the night, and unwraps himself during the night, and often I don't need to rewrap him, he just goes back to sleep without it.

I bought a grobag the other day, and will be trying that out once I've washed it. But I may still need to wrap his arms over that for the initial sleep. Like I said, he's really at an inbetween stage at the moment.
