When I weaned my Ayla off the Swaddle... I layed on on her side to sleep. With her arm pinned and her cheek next to the mattress I think she felt secure, similar to a swaddle. I also made small fuzzy blankets and tucked her in essentially from the shoulds down, not tight at all, but again enought to feel cuddled and secure... she weaned off the swaddle gracefully with this technique. It may be worth a try.
