They aren't the first, but they are definitely the best. The new Fridababy TherMonitor is a smart new gadget that you'll love. Your baby wears it at night and it will alert you if your child develops a fever. Pretty cool, no? When baby’s sick, the last thing a parent wants is to wake him or her for a temp check. FeverFrida checks in on your babe every four seconds without waking him or her, thanks to a bitty Bluetooth monitor and patch placed under the arm. The FeverFrida will alert your smart phone or tablet when the temp goes above a predetermined threshold and continuously stores data for pediatrician visits and medicine dose reminders. Think thermometer meets very smart baby monitor!
