The best baby thermometers for your baby, their room, and the bath

Best baby thermometer

Every family medicine cabinet needs to have the best baby thermometer for when you think your child might have a fever.

Gone are the days you needed to shove a mercury-filled old-school thermometer in your child's armpit and try to hold them still for six minutes to get an accurate reading. Thankfully, technology has advanced so much that we can get a pretty accurate body temperature reading in just a few seconds. In addition to fever thermometers, bath and baby room thermometers are also necessary to make sure that your baby's surroundings are just right. 

Choose the best baby thermometer for your child

There's a large choice of baby thermometers on the market that cost anywhere from £10-£50; here’s a run-down of the different options available:

  • In-ear thermometers: You’ll notice most doctors use a digital in-ear thermometer to take babies’ temperatures —this is because it is quick and painless, while giving an accurate body temperature reading.
  • Non-contact thermometers (forehead): These work by taking an infrared reading from your baby’s forehead, meaning you can check on their temperature with no physical contact. Don’t confuse these with the cheaper strip forehead thermometers, which are very different, and much less accurate. The NHS recommends avoiding using forehead strip-type thermometers.
  • Armpit thermometers: The NHS still recommends these when taking your baby’s temperature —especially when they are a newborn.
  • Room thermometers: These can help you make sure that your baby's room is the safest temperature for a baby. Experts suggest 16–20°C with a light blanket.
  • Bath thermometers: A baby's bath should be 37-38°C and the only way to make sure you've got it right is with a baby bath thermometer.

What is the normal temperature for a baby and what is a fever?

The normal temperature for a baby can range from 36.4°C to 36.8°C, but each baby has a slightly different core temperature, so this could vary. It’s a good idea to take your little one’s temperature when they are well so you can get a good idea of what their normal, healthy temperature is. The NHS urges parents to seek urgent medical advice if their baby under three-months-old has a temperature of 38°C or is between three and six-months-old and has a temperature of 39°C.
