I tend to think if your DS doesn't need to be wrapped to sleep then stop now. I wrapped mine religiously and weaning him from it was really hard. We basically had to stop when he started rolling because he would roll onto his tummy in bed and get stuck, so it had to be done quickly and caused quite a few weeks of bad sleep. Next time around I plan on stopping very early on (providing of course bubs sleeps ok without it, DS did in the early days).
