Hi Corelly,
Thanks. We had used sleeping bags before and so I did try one again last week during one of his day time naps. I was going in so many times to re-position him, so looking to try anything. The sleeping bag helped the first time. But then he worked out how to roll with it on (and the harness) and so we gave up. I might try again now though at night as its starting to get a bit cooler.
