Are baby swings safe for sleep?

No. Across the parenting subreddits in our source set (r/ScienceBasedParenting, r/newborns, r/BabyBumps, r/Mommit) the consensus is unambiguous: swings are not approved sleep surfaces. Reviewers consistently note swings are useful for supervised soothing and hands-free time, and that babies should be moved to a flat, firm sleep surface once they doze off. Consumer Reports coverage referenced in our signals echoes the same safety framing.
