We preferred the Halo to the Swaddle Me - LO hated how constrained the legs were on the Swaddle Me. Thankfully we were able to unswaddle before she became too small for the Halo, but I was ready to sew on some velcro to the back of a larger sack so I could continue to swaddle. If you check Amazon, there is another brand that offers swaddles pretty large, but they are more like the swaddle me, nothing like a sack.
