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 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!

FeverFridaTM The iThermonitor is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from FeverFrida is the best! FeverFrida is on the high end of the price scale but, when compared to other instant thermometers, it really is not that expensive. To be able to reliably see what baby’s temperature is, especially at night, without having to bother baby or wait for the thermometer reading is well worth the cost. If baby is in a separate room you will not be able to receive alerts should baby’s temperature reach a high level. But you can see the entire night, or days, worth of temperatures, which you can not do with any other thermometer. You do need to be within 10 feet of baby to receive the data. Personally I think the positives outweigh the negatives and would strongly suggest the FeverFrida.

Rated 5 out of 5 by from This is such a huge help and relief for my family...my daughter has a periodic fever syndrome and gets fevers every 3-8 weeks...this works so well and keeps my mind at ease. The app is very easy to use and keeps us updated constantly!

May sound like a silly question but can this thermometer be used on a baby with a pacemaker? Baby pacemakers are placed in the upper abdomen region. Wondering about any interference.Preparing for a baby with complete heart block so this is very important!

Thank you for reaching out regarding Fridababy's FeverFrida! We recommend that you reach out directly to your physician about this matter. Please let them know that the data between the FeverFrida and the iThermonitor app is transmitted via low-energy Bluetooth to see if there will be any impact to the pacemaker.

I am trying to determine the best placement I read "armpit skin" in the manual but all the pictures seem to be at or slightly below nipple Level. Also is it better to place it vertical or horizontal?
