Not as directly as the question suggests. Yes, swaddling can lead to SIDS, a baby if not swaddled properly can still roll over if they manage to unfurl the swaddle. It is the act of rolling over that leads to SIDS, not the swaddling. Or rather it is the Blanket that causes the SIDS, not the swaddling. This is exactly the purpose of the SNOO Sack, it allows you to swaddle your child, which has many benefits, but actually leaves much less chance of SIDS due to its design. You can’t mess up putting the baby in the SNOO Sack, so the chance of SIDS are largely decreased.
