When Tyler got to be around that age, we moved to the Aussie swaddle with a bedsheet (directions are at the top of this forum). He just couldn't settle without a swaddle, so we knew it wasn't time to wean him yet, but he was wiggling out of his regular blanket swaddle almost as soon as I laid him down. IMHO, if he settles with a looser swaddle or none at all, then he's ready to wean it. There really isn't a specific age to wean the swaddle. For us, we weaned Tyler back to a regular blanket, legs-only swaddle around 8 mo or so. It had become a part of his nap routine (we never swaddled at night for some reason) and had strong sleep associations, so we just stuck with it...to this day, we still wrap his legs at naptime, and he's 20 mo! HTH!
