Great thread, have been wondering this too. DD still has her 'blankie' which is just an old muslin wrap we used when she was a baby.

I was thinking of using one of the muslin wraps my mum made for DS which he is too big for now, going to cut it in half so we have two.

I'd much rather he have this than a dummy (he currently has a dummy on and off but I really want to get rid of it!)

Gosh, if only these little people would sleep hey??
