Making sure your baby’s room is at a safe temperature and isn't too hot or cold is important, so investing in a baby room thermometer is often a good idea, allowing you to check the room temperature at a glance.
What temperature should my baby's room be?
A safe sleeping temperature for your baby’s room is between 16 and 20 degrees. According to The Lullaby Trust, the chance of SIDS is higher in babies who get too hot, so keeping your baby’s room at a comfortable temperature is important.
How can you check if your baby is too hot?
Obviously, every baby is different, and even if you’ve used a room thermometer, it’s important to check your baby regularly to ensure they are not too hot. This can be done by simply feeling your baby’s tummy, or the back of their neck, as their hands and feet will often be colder than the rest of their body. If your baby feels hot or sweaty, remove layers.
If you’re worried the temperature in the room is too hot, especially during the summer months, open the bedroom or a window if it is safe to do so before putting your baby down to sleep. If you’re using a fan to cool the room, ensure it is not aimed directly at your baby.
Make sure your baby has sufficient fluids if bottle-fed and if your baby's room is difficult to cool, make sure to use lighter bedding and clothing.
As time goes on you'll learn about your baby, so it will become easier to check their temperature and know what's normal.
How can I ensure my baby’s room is warm enough?
Despite feeling cold in the winter, you will rarely need to keep your heating on all night, but if you do, ensure it is set to a low temperature no higher than 20 degrees. It’s often a better idea to add another layer to your baby. Remember, it’s important not to put a hat on your baby indoors as they maintain body temperature by releasing heat.
Another good way to keep an eye on room temperature is to have a baby monitor with a screen - this can also alert you of the room's temperature and for example, in the winter if you've got the heating cranked up too high, you know sooner rather than later when to turn it down.

What are the best baby room thermometers on the market?
From those that double as night lights to dual-purpose thermometers that can also be used in the bath, investing in a baby room thermometer can tell you at a glance whether or not a room is safe to sleep in. We’ve hand-selected the best on the market here:
Tommee Tippee Gro-Egg Room Thermometer
The best baby room thermometer nightlight
This clever little room thermometer shows you at a glance whether the temperature of your baby’s room is ok. It glows blue if the room is too cold, red if it’s too hot and stays yellow when the sleep environment is safe. Not only does it save you having to test your eyesight in the middle of the night, but the glow also acts as a gentle nightlight for your little one.
The only downside we can find is that it needs to stay plugged in, so is not too transportable, but this is only a small price to pay for such a great product.
Review: "This was recommended to us by staff in Neonatal. I have seen many reviews saying it's inaccurate. I did notice when placed near a patio door temp dropped or near a light or TV, it raised due to appliance heat. So we centred the cot in our room and placed the egg next to the cot and it seems to give a fairly accurate reading. It's not been off yet. Their leaflet is extremely helpful in terms of how many layers and clothing is required at certain temps. I found the leaflet is full of invaluable information. We are over the moon with it. And saves us guessing and worrying. We regularly check our baby's temp and so far the egg has been fantastic to regulate temp."
Tommee Tippee Closer to Nature Digital Bath and Room Thermometer
The best multipurpose baby room thermometer
Another great little dual-purpose baby thermometer, the Tommee Tippee Closer to Nature thermometer can be used in the bath and bedroom. Stand out features include the LED warning light, which lets you know when the bath is getting too hot. It’s also got a really nice, clear, easy-to-read screen.
Review: "So pleased I bought this during pregnancy. It was bought for when baby arrives, but I bought it around 26 weeks so that I could use it in my bath being pregnant as I'd avoided baths during pregnancy due to the risks of pregnancy and overheating. I have been able to enjoy baths again keeping them at a safe temperature, as well as monitoring the temperature in our room and the babies room to order correct bedding etc for their arrival which is any day now. We initially thought it wasn't working as you have to tap it (sometimes a fair good tap!) to activate the screen. But I'm very pleased I bought this thermometer."
Happy Family Jungle Animals Nursery and Room Safety Temperature Thermometer
The best budget baby room thermometer
A large thermometer card display that allows you to see the temperature of your baby’s room at a glance. An affordable option with a cute animal design, fix this room thermometer on the wall near your baby’s cot to ensure their sleep environment is safe.
The downsides are that unlike others in this category, this thermometer will not give you a precise temperature reading and it’s not transportable.
Review: "The thermometer is quite accurate if you're looking for a cheap alternative. It’s been 3 months since I have placed this in my baby’s nursery room and it’s still working fine. It gives a great look for a nursery and is very handy at the same time."

DOQAUS Digital Hygrometer Indoor Thermometer
The best no-frills baby thermometer
It may not be the prettiest room thermometer on the market but it's certainly clear. It has a fast response for peace of mind, measuring every five seconds to provide updated and accurate readings. It also has a moisture meter with a humidity level icon indicating ambient status.
Some reviewers have said that the thermometer is smaller than expected but still does an excellent job.
Review: "Does the job! Really is tiny (thumb size) so quite easy to hide if you don’t want it on show. Is much more accurate than the temp on our baby monitor."
Miniland Bee Shaped Bath and Environmental Thermometer
Best for quick temperature reading
A pleasant and fun bath and playmate in one, under any circumstance. With alerts for both high or low temperatures, the bee warns with a green light when the water temperature is lower than 30ºC and with red light when it is greater than 39ºC. In addition, it shows arrows on the screen indicating that the water temperature is out of the comfort range.
Aside from the digital clock, thermo bath also has a stopwatch with a countdown and count forward which allows parents to control bath time. Parents love the durability of this and kids will love playing with it during bath time!
Review: "Excellent product. I'm buying another as a gift it's so good. Easy to use just pop it in you're bathwater. It measures the temperature constantly with a temp display. And also a timer so you know how long the baby has been in the bath. No need to keep checking the display though as it has a really handy light that beeps green to show the temperature is ok. And then Red when the water is getting too Hot or too Cold. The only thing is it was a bit awkward trying to set the time at first, but that is probably my fault as typically tried without reading instructions. Looks cute and also came with a warranty, another plus."
