Many of the reviews that we read had negative things to say about the thermometers included in grooming kits. A thermometer is not the primary purpose of a grooming kit, it is an extra bonus item. Thermometers that must be placed in a baby’s mouth or armpit are incredibly difficult to use correctly. Temperature strips that are placed on your infant’s forehead are just for reference so you know if their temp has spiked. We highly recommend looking into getting a high-quality thermometer for your infant. Grooming kit thermometers are good for quick reference, but a higher quality thermometer will give you a more accurate reading.
