Child safety is critical, yet most parents can't monitor their children 24 hours a day. In those moments when children are out of sight or earshot, connected or smart devices can step in to play the role of guardian. At this week's Internet of Things World 2017, we found three revolutionary products that can help you protect your children, even when they're out of reach.

Owlet Baby Care (iOS, Android)


The fear of Sudden Infant Death Syndrome (SIDS) alone can trouble a new parent's sleep. That's where Owlet's Smart Sock 2 ($299) comes in. This comfy fabric smart sock that you slip on your baby's foot uses a combination of pulse oximetry and tech to measure a baby's heart rate and oxygen levels during sleep. If levels are higher or lower than preset ones, you are notified on your phone via the Owlet Baby Care app and a Bluetooth-connected base station that promises to get your attention with lights and sounds. Even when things are fine, you can view real-time info on your phone via the accompanying app. That way you can rest assured that you and your baby get a better night's sleep.

Tinitell (iOS, Android)


Children can face danger, just walking to or from school or when out with friends. The Tinitell watch ($149, plus $9 per month service fee), which comes in four colors, is a SIM-ready wearable wrist phone and GPS tracker that when paired with the Tinitell app can be used by your child to quickly reach up to 12 stored contacts. Also, with the app installed on your phone, you can call your child and find them on a map through GPS locations, thanks to Google Maps integration.

Grush Toothy Castles (iOS, Android)


OK, so poor dental habits aren't life-threatening in the immediate, but tooth decay and gum disease have been linked to the onset of heart disease, diabetes, Alzheimer's disease, respiratory infections, and fertility issues, in adulthood. Grush: The Gaming Toothbrush for Kids ($59) gamifies tedious brushing by transforming it into a fun, interactive game. The advanced bluetooth motion-sensing toothbrush pairs with interactive and educational mobile game app Grush Toothy Castles to guide kids' brushing. After a full two minutes, kids are presented with a score, or "Grush Factor," based on technique and consistency. Parents can then track the results to ensure that children are brushing adequately and hitting all the hard-to-reach spots.
