Gadgets promise peace of mind—like heart rate or movement sensors that attach to your baby or their crib. But the FDA is warning against most of them. If a device says it will do this, the FDA advises avoiding that product entirely. The FDA doesn’t name names, but when I searched for “wearable baby monitor” on Amazon and on Google Shopping, most of the brands that popped up are ones that aren’t in the FDA’s database. If the product is in the database and the classification product code is QYU, it’s been evaluated and authorized by the FDA.
