It can make a difference between a relaxing and comfortable bath experience for your baby or one filled with pain. 

What Is An Ideal Baby Bath Temperature

The normal baby’s bath temperature should be around 98.6–100.4°F (37–38°C). Babies have thinner skin therefore they need cooler bathwater than adults. You can check your baby’s bath temperature using a water thermometer.

Types Of Bath Thermometer

The different types of bathwater thermometers available in the market are;

Floating Bath Toy

These types are made in the shape of an animal but have either a digital display or a color-changing area that shows when the water is either cold or hot. They are waterproof, float, and give an accurate temperature reading. Examples include Mothemed Whale, B&H Duck, and the Turtlemeter.

Don’t be deceived by their toy structure, instead clean and care for them more than you will do for other regular toys.   

Bath And Room Thermometer

These types do double work. They are relevant and work in the tub and also your little one’s room. Examples are Mothermed and Famidoc thermometers.   

Digital vs. Analog

Most bath thermometers require batteries and make use of a digital screen to display the temperature. There are a few ones like White Hot Ducky that are battery-free and display when the water is too hot but not at the actual temperature.

Factors To Consider When Choosing A Bath Thermometer

Although the structure of a bath thermometer is important, safety and function should be the priority features driving your decision. Below are a few tips to consider when choosing a baby bath thermometer.

  1. Non-Toxic Materials

Several parents are familiar with purchasing BPA-free products, whereas there are better options made from food-grade plastics that are super safe. A good example is a Mothermed thermometer.  

  1. Temperature Display

You have an option of selecting between using a thermometer that uses a digital display making it easier to read at one glance or the analogy style thermometer which might not be so easy.

  1. Continuous Reading

Consider a baby bath thermometer that will take a continuous reading while you bathe your little one instead of those that only take a reading at the beginning. This will be helpful for longer baths where you can be sure the temperature of the water has not gone too low.

  1. Temperature Alarm

Thermometers with a temperature alarm can let you know when the water is no longer ideal or safe for your baby. For instance, the Mothermed has a visual alarm that has the form of a red light that indicates too hot, and blue light that indicates too cold, making it super easy to use.

  1. Fahrenheit vs. Celsius:

Some thermometers display Fahrenheit and some Celsius, whereas others display both. You will have to double-check the different types of bathwater thermometers if you have a strong preference.

  1. How To Check The Water Temperature Of A Bath Without A Thermometer?

Hold your hand above the water and dip your elbow inside the water. You will be able to get a rough idea of the temperature of the water within 10 seconds. 

  1. How Do I Know If A Thermometer Is Accurate?

To check the accuracy of a thermometer, we need to insert the stem of the thermometer into the ice water in such a way that the stem is an inch deep without touching the glass. Within a minute, the thermometer will register the reading of the ice water. Where the reading is 32℉ or 0℃, the thermometer is assumed to be accurate.

  1. Is Baby Bath Thermometer Safe?

Baby bath thermometers are specifically designed for safety. They track your baby’s bath water to ensure it never gets too cold or hot. They are designed to be waterproof and usually have a built-in battery. 

  1. Why Should I Use A Baby Bath Thermometer?                         

Baby bath thermometers are fun ways to keep your baby safe during bath time. It is a simple way to avoid accidental injury resulting from too hot or too cold water because bath thermometers check the temperature of the bath water and notify you with an alarm of the temperature of the water. 

  1. How Do Baby Bath Thermometers Work? 

Bath thermometers don’t work the same way. Some are activated by shaking while others may just require placing them in the water. Whichever one is yours, make sure to pay attention to the temperature level shown on the screen to be sure of the safety of the water you are about to use for your little one. 

Final Thoughts

Along with using your bath thermometers, note that the room temperature is a major factor at bathtime and so must be checked too. Maintaining a baby’s body temperature, in and out of the water will not only keep them calm, but it will also give you rest. 

Make sure to fill the baby bathtub with water that reaches to the belly button before placing the baby inside it. This will help you have enough to rinse your baby immediately as you wash him. I will also recommend that you consider using non-toxic bath products like Aveeno Baby Daily Moisture Wash & Shampoo, Johnson’s Head-to-Toe Wash & Shampoo and CeraVe Baby Wash & Shampoo.
