Why you need a thermometer?

You can feel and express, but your baby just can feel and not able to express his/her feelings when too young. You should always keep a thermometer in your home and if you do not have, then buy a thermometer immediately. Moreover, like other necessary elements of your home, a thermometer has also that mark.

But, as I said that, you need a special digital thermometer for your baby. In addition to that, all the types of thermometers will not give you an accurate result. Therefore, you need to buy the perfect thermometer for babies. There are many brands of thermometer on the market which are specially made for babies.

Why should use digital thermometer not Old Mercury Thermometers?

Using of mercury thermometer is alright as long as you use them correctly. But, if you break it, the problems will start. Moreover, an improper disposal of mercury thermometer can lead to serious environmental and health hazards as well. Mercury is basically a toxic metal and it may cause severe neurological disorders.

On the other hand, there are many brands of non-mercury thermometer on the market. The main component used in a non-mercury thermometer is non-toxic alcohol instead of using mercury. They are also called a spirit thermometer or alcohol thermometer and alcohol measures the temperature.

Like as mercury, the alcohol of digital thermometer gets expanded in volume while it gets warmer and leads to the rise of the liquid inside the glass thermometer.

So, you should go for a digital thermometer as it provides an accurate result in a less amount of time.

How a digital thermometer works?

The temperature measuring device present in a digital thermometer is called thermoresistor. A thermoresistor has both electrical conductance and resistance capacity. Electricity conductance or resistance shifts with the temperature and thus a digital thermometer calculate the temperature with the help of the thermoresistor. Moreover, a little computer or other electrical circuit measures the resistance, converts it to the temperature and show the result on the display.

Types of Baby Thermometers

I have already said that, to measure your baby’s body temperature, you need some special types of thermometer for babies. Now I am going to talk about some types of thermometers which are specially made for babies.

  1. Rectal thermometers: Using a rectal thermometer can be considered as the best way to measure a baby’s temperature. You may think this can create an uncomfortable situation for babies, but they are very effective in measuring a baby’s body temperature. Moreover, if you want to buy a best rectal thermometer for your baby, you need to seek for a wide base and a short tip thermometer. Because, these characteristics will prevent it from inserting too much which can create a severe situation.
  1. Temporal artery thermometer: These types of thermometers are one of the latest types of thermometer for babies. Although they are much expensive, but they are much more effective in showing accurate result. The basic function of the thermometer involves using an infrared technology to scan and measure the temperature of the temporal artery of the forehead. They are much safer and convenient since, you do not actually need to touch your baby. Moreover, the accuracy of the thermometer has been granted by the specialist and so they have also used in hospitals. Along with that, they are perfectly suitable for the children from three months and older. On the other hand, specialists suggest that, you need to go for a double- check with the rectal thermometer if your baby is under 3 months old.
  1. Armpit thermometers: Although these types of thermometers have a less accuracy, they are also less invasive. Moreover, they are cheap in cost. But, I like to suggest you buy digital thermometer.
  1. Ear canal thermometers: These types of thermometers are common and less invasive as well. Moreover, they are much easier to use. The function of the thermometer involves placing it in the ear and it will give an accurate result in children over 1 year old. On the other hand, since it needs to place the thermometer in the ear, it may be uncomfortable for the babies less than 1 year old because, their ear canal opening is too narrow. So, it is better to use in children over 1 year old.
  1. Oral thermometers: Oral thermometers are safe, cheap and easy to use. Moreover, it basically provides an accurate result. To take the temperature using it, just place it under the tongue of your baby and wait for a while. These types of thermometers are specially a good option for the children over 4 years of age.
  1. Pacifier thermometers: These are thermometers which are built into a pacifier, meant especially for young children. Although you may think about them as an ideal choice, but they are not actually recommended by the pediatricians since they do not provide an accurate result.

The perfect thermometer for babies according to age

  1. 3 months and younger: The pediatricians usually recommend to use a best rectal thermometer for babies with 3 months or less than 3 months old. Moreover, they usually provide the most accurate result. So, if you think your baby got a fever, then you go for a double- check with the rectal thermometer. Moreover, since your baby is too young, you may consult with your doctor to learn the use of a rectal thermometer correctly.

So, if want to buy one, I like to suggest you to buy the safety 1st gentle use rectal thermometer.

  1. 3 months and more: If your baby is more than 3 months, then you should use a forehead or temporal artery thermometer. Although the instruction of use this thermometer is not much easy, but a little practice will help you to come up with. To use it, you just need to gently touch your baby’s forehead and observe the temperature carefully. To use it, just place it at the center of your baby’s forehead, press the button and gently swipe it across the forehead. After that, you will hear a “beep” which will ensure you that it works nicely.

So, if you are going to buy a temporal thermometer, I suggest you to buy the Exergen Temporal Artery Thermometer.

Normal body temperature for a baby

It is important to know the normal temperature of a baby. Although the temperature varies a little bit, there is a normal body temperature range for babies. The temperature is about 36.4 degree Celsius for a healthy baby. On the other hand, if there is a fever, the temperature may rise to 38 degrees Celsius and more.

Your baby may have a fever if he/she:

  • Feels warmer than usual (forehead, back or stomach)
  • Feels sweaty
  • Has flushed cheeks

So, if you think that your baby got a fever, then check the temperature with a digital thermometer and consult with the pediatrician to get medical advice.
