We triple swaddled last night and DS is finally back to STTN. Yay. We did the double swaddle, around the arms and up between the legs, underneath a swaddleme. He was STTN since about 7 weeks old then 2 weeks ago he started waking up at 5am, 6am and 7am just to be re-swaddled.
We tried weaning him of the swaddle, but he's just not ready yet. I don't care if I swaddle him until he goes away to college, as long as I get to sleep.
Re: Triple Swaddle Success
I did this swaddle:

then put him in a swaddleme to keep his legs confined. DS loved it.
I use the escape proof swaddle, which I guess could be called a double:
