I voted college, too, but sd is only 6.5. Now he isn't swaddled to sleep anymore, but he has sensory issues so he does get "swaddled" now and then, still.
But as a baby when he would start to act like he didn't like it we'd just try a different blanket and do it longer. Even though he always nursed to sleep it was still important for him to stay alseep.
IME working with babies I've found all babies (that I've encoutered) want to be swaddled, and for months and months, it's just that a lot of parents aren't very good at it, or worry that the baby doesn't like it. Just remember, the tighter, the better!
