Best for: Vitals peace of mind for healthy babies 1–18 months, anxious first-timers
The FDA-cleared wearable that tracks pulse rate and oxygen — the vitals monitor for parents who want numbers, not just video.
Owlet's Dream Sock wraps the baby's foot and reads pulse rate, oxygen saturation, and sleep state — the only major consumer baby monitor with FDA clearance for its Health Notifications feature. That clearance is over-the-counter and covers healthy infants roughly 1–18 months (6–30 lbs); it is not a clinical alarm and not intended for preterm or medically fragile babies. The base station glows green when readings are in range; the app trends sleep quality nightly. No camera included (pair with any video monitor). For parents whose anxiety is about vitals rather than visuals, this is the category answer.

Cleared, not approved — a lower bar, and the difference matters. Owlet has FDA clearance for the Dream Sock's Health Notifications feature (pulse rate and oxygen saturation) as an over-the-counter product for healthy infants roughly 1–18 months and 6–30 lbs. It is not a hospital-grade alarm, it is not cleared for preterm or medically fragile babies, and it is not a substitute for medical care.
No. No monitor prevents SIDS, and Owlet doesn't claim to. The AAP explicitly does not recommend home cardiorespiratory monitors as a strategy for reducing SIDS risk, and cautions that they can create false reassurance. What actually lowers risk is AAP safe-sleep practice: back sleeping, a firm flat surface, a bare crib, and room-sharing without bed-sharing for at least the first 6 months.
Owlet reads pulse rate and oxygen from the foot; Nanit watches sleep from above. Note that neither measures breathing directly and neither is a diagnostic device — if you are worried about your baby's breathing, call your pediatrician rather than buying a monitor.
No — live readings and notifications work without one. That's a real advantage over Nanit's Insights model.
