Taurean - I just looked those up, they look great. Think I'll invest for this baby.
They're well worth it. I borrowed a couple from a friend and DD2 loves them. I tried transitioning her to a GroBag last night (DD1 transitioned fine at 9ish weeks) but she didn't settle until we put her back in swaddle bag - and she went straight to sleep I'm going to buy the next size up and will try the 50/50 ones to transition her to arms out. They're such a great idea.

BTW, we were taught to swaddle our girls in hossi but I did notice the swaddle was always wider (looser) around their legs giving them a bit of room to move. The focus seemed to be more on their arms and chest but I was personally under the impression that 'the tighter the better' was the way to go.
