As first-time parents, we were drowning in newborn wake-ups. After trying everything from white noise machines to swaddles, we found 3 evidence-backed sleep aids that made a real difference: a temperature-regulating sleep sack, a responsive sound machine, and a smart crib monitor with gentle wake-up alerts. The combo helped our baby sleep 6-hour stretches by 10 weeks — and us too. These aren't gimmicks; they're science-informed tools that support natural sleep development. If you're exhausted and skeptical, start with the sleep sack — it's affordable and instantly noticeable.

TL;DR: Three baby sleep products that actually work — backed by pediatric sleep principles and our real experience. No marketing fluff.
