What to Look For In a Baby Bath Thermometer?

Accurate reading: Accuracy is primary for thermometers. Why would we invest in a thermometer if it does not read the right temperature?

Min/Max temperature alarm: Most baby bath thermometers have alarms that ring when the water temperature reaches the max/min limit mentioned. 

Proper and Safe Material: Since these thermometers are for babies, make sure to grab one with excellent and safe material use. Using thermometers that are poorly made can cause skin irritation and rashes for your little one.

Waterproof: Some thermometers run on batteries. So make sure they are waterproof and prolonged exposure to water does not damage the device. 

Generally, the water’s ideal temperature for bathing toddlers should be just above 100 degrees Fahrenheit (37.7 degrees Celsius).
