FAQs about Baby Bath Thermometer

1. Are baby bath thermometers safe?
Yes, baby bath thermometers are designed for safety. These tools are a super simple way to keep track of your baby’s bath water to make sure it never gets too hot or too cold. Bath thermometers are designed to be water proof and often have a built-in battery. The bath thermometers that do not have built-in batteries will have a water sealed battery chamber to prevent leaking. By utilizing a bath thermometer, you can help prevent an accidental burn from too hot of bath water. They are also useful when your baby has a fever if you’re hoping to bring their fever down by allowing them some time to soak in a cooler bath because this can help you target the best temperature for your baby given each situation.

2. Why use a baby bath thermometer?
Baby bath thermometers are a great way to keep your baby safe during bath time. Babies frequently get burned from bath water that is too warm and a bath thermometer is a simple way to prevent this accidental injury from occurring. Bath thermometers frequently check the temperature of the bath water and even notify you with an alarm when the water becomes too hot or too cold. Bath thermometers also help prevent your baby from getting too cold. Since younger babies are more sensitive to temperature extremes, thermometers allow you to keep your baby safe and comfortable.

3. How do baby bath thermometers work?
Every bath thermometer will work a little bit differently. Typically, bath thermometers can be easily turned on either by shaking or automatically by being placed in the water. Once you have your thermometer in the water just simply pay attention to the temperature on the screen to ensure that it isn’t too hot or too cold. We recommend checking your baby’s bath water temperature before they get in the water whenever possible. Most bath thermometers are designed to look like a bath toy so your baby will likely enjoy having it floating around in the tub with them.

5. What temperature should baby’s bath water be?
Typically, it is recommended that baby bath water stays around 100 degrees Fahrenheit or 38 degrees Celsius. Some parents choose to give their older babies or toddlers a cool bath when they come down with a fever, so in this situation you would want to use a cooler bath temperature. You should also ensure that the room is kept comfortable and warm for your baby since they can easily get cold once taken out of the water. Luckily, many bath thermometers also test the room temperature as well. Younger babies are more sensitive to temperatures so it is important to pay attention to the bath water temperature for your baby to prevent them from getting too hot or too cold.
Conclusion
There are plenty of options when it comes to choosing a bath thermometer including simple designs as well as thermometers that are designed to resemble a bath toy for your child. Some thermometers offer additional features such as multiple units of measure and detecting the room temperature as well. Ultimately, any bath thermometer will be a great choice because it will allow you to keep your baby safe. All bath thermometers are equipped with a hot water alarm that will sound if the water reaches an unsafe temperature. It is important to always check the temperature of the bathwater before your baby gets into their bath.
