Every second counts when your baby appears to be unwell. Naturally, one of your first steps will be to whip out a thermometer to check for a fever. At that moment, you’ll want a tool that you can trust to provide a reliable, precise temperature as quickly as possible. Below, we have several types to choose from so you can be prepared when the time comes.

Keep in mind: when you’re taking your newborn’s temperature, you can’t just stick a thermometer in his or her mouth like you would with an adult. For children under 3 months of age, you should take their temperature rectally, and any fever over 100.4 at this age requires an urgent call to your doctor and a trip to the emergency room. Once children are over 3 months of age, you can take their temperature with a temporal artery thermometer which reads the temperature on the forehead, and after 6 months of age with a tympanic thermometer which goes in the ear. But, rectally is the most accurate form of temperature reading and digital thermometers are the only ones suitable for children (do not use those that contain mercury). Once your child is around the age of 4 or 5, you can start taking their temperature orally or when they can hold it under their tongue. And remember, taking a baby’s temperature right after a bath will give you an elevated reading, so in those situations, you’ll want to wait a few minutes before breaking out the thermometer.

This oral and rectal Provèn thermometer works for both babies and adults, so you can have your whole family covered. It takes just 10 seconds to determine a temperature, and it’s waterproof for easy disinfecting.

The product provides highly accurate readings, and reviewers rave about its flexible tip, which makes it more durable and comfortable to use than standard thermometers with a more rigid tip. It’s also a cinch to clean—especially important if you are going to use it rectally.

Best Budget: Fever Fighters Hassle-Free Forehead Thermometer Strips

Not everyone in the medical community recommends thermometer strips, as they’re not necessarily as accurate as some other tools out there. However, if you’re in a situation where a regular thermometer is too invasive for your baby (say, when your child is sleeping), these strips from Fever Fighters can get the job done quickly. Just press it to the forehead and you’ll have a reading within seconds. You’ll see the colors change to indicate the temperature in both Fahrenheit and Celsius. When you’re finished, wash the strip off with soap and water and place it back in the thin case for storage.

Travelers like to bring this product in case of an emergency, as it’s cheaper and easier to throw into a bag than a regular thermometer. The strips are also great for fussy children who just can’t sit still for a reading. And if you have older kids as well, reviews suggest that they might actually think it’s fun to get their temperature taken this way!

Best Ear: Braun ThermoScan 5 Ear Thermometer

Braun’s gentle thermometer makes frequent appearances in pediatrician’s offices because it’s so simple and reliable. The pre-warmed tip ensures that the findings will be more accurate (many other ear thermometers have cool tips, which can unintentionally lower the readings).

Best Multipurpose: Health Guardian Infrared Digital Thermometer

No matter how you normally take your baby’s temperature, it’s always good to have a backup plan. This multipurpose Health Guardian digital thermometer has dual modes so you can switch between the ear and the forehead, depending on your situation. Whichever way you choose, it takes just one to three seconds, and the color indicators will help you decipher the findings (green means normal, orange means light fever, and red means you’re reaching more dangerous territory) without lots of loud, disruptive beeping. And if you’re monitoring your kid’s health, you can access up to 35 previous temperature readings thanks to the Memory Recall function.

Shoppers who tried this product like its versatility, especially when dealing with ear infections or struggling children. They say the thermometer fits well into little ears, provides accurate readings, and ultimately works great for the entire family.

Even better: you can also use it to find out the temperature of a room or an object (a baby bottle, for instance). Turn on the quiet mode setting and your child won’t even need to know you’re nearby while you check.

Customers find it useful that in addition to their baby’s temperature, they can also use this tool to check other objects. Plus, when there’s no need to touch the skin, you also don’t have to worry about sanitizing the thermometer afterward—making the process move extra quickly.
