When babies sleep it is both a wonderful and slightly unnerving time. If you have a baby, you have absolutely watched them sleep just to be sure that they’re still breathing. Let them rest and get some peace of mind instead with the Owlet Sock + Cam, the sock that monitors your sleeping baby.

This little sock tracks your infant’s heart rate and oxygen levels while they’re slumbering peacefully. Which is means that you too can slumber peacefully which is always nice. It will also give you notifications on how your baby is doing so you don’t have to worry about them being in distress.

It comes with a camera and acts as a baby monitor that syncs with your smartphone. SIDS is a real concern and it’s not like your baby can tell you if they’re not doing so hot in the middle of the night. This little device can go a long way to helping parents get some extra sleep. You can get the whole system for $399.
