Pacifier and SIDS

I read that babies who use a pacifier while napping and sleeping are less likely to get SIDS, but we have never used one with our 7 week old. She never needed one to fall asleep, so we just didn’t bother. But now that I read this, I am wondering if we should have! Should I try to introduce it now? And if so, what is the best way to do this? Thanks!
