I've read that babies will just outgrow swaddling on their own (some don't like it from the beginning and for others they need it a lot longer than the norm)... so if they fit in the blanket and it is the way they will sleep I would still go for it
I check on the infant during her naps, and she never rolls while she sleeps, but if she does, I will have to rethink it. Good idea to have arms free
