I'll agree with that advice, do what's best. If bubs will only sleep that way then why stop. I too thought I needed to stop a while ago & it just didn't work, he had found his hands but still doesn't know exactly how they are working - so he'd pull out his dummy then wave it about crying. Most people I've spoken to say bubs just grows out of it on their own. I suppose they get to a point where they know what to do with their hands and they don't want them wrapped up. I'm just going to wait til he's ready & Charlie is 21weeks. I also tried the one arm & it just seemed really silly to me, one arm flapping about. I was given some advice that might work for you if you want to keep trying - that was to just put the wrap around their tummy. That way they still have the wrap around them but arms are out. Or start lightly wrapping, letting the arms come out as they put themselves to sleep.
