Whatever the weather, put your baby to sleep on her back and be careful not to let her become overheated.
Whether your are dressing your baby in winter or caring for your baby in hot weather, a safe room temperature for your baby's bedtime remains pretty much the same.
Here's what you need to know about the room temperature your baby should sleep in...
What our expert says
What's the right temperature?
It's important to make sure your baby's room is the right temperature. While you can get up when you are hot, take off layers and use a fan to cool down, your baby can't manage her temperature so easily. Babies do not need hot rooms, all night heating is rarely necessary.
"Anywhere between 16ºC and 20ºC is a good temperature for your baby, and around 18ºC (65ºF) is ideal," says Jennifer Ward Head of support and development at FSID (fsid.org.uk). "That's actually cooler than most people would expect the ideal temperature to be."
Try to keep your baby's room temperature constant. "Use a room thermometer so you can see the exact temperature in the room and keep an eye on it," says Jennifer.
Running heaters or air cooling devices during the night, to maintain an even heat, is not very practical and can also cause the air in your baby's room to become too dry which can lead to coughing or dry skin.
What should I do when it's warm?
If your baby is finding it too stuffy to settle, close the curtains and open some windows to allow a breeze to flow through the house to cool your baby's room. "Make sure your baby's cot is not in direct sunlight and keep the room as cool as you can," advises Jennifer. "There are certain summers days when you aren't going to be able to get the room to the ideal temperature, but you need to make sure that you are keeping your baby as cool as you can by letting in a breeze."
Choose lighweight blankets and clothing for your baby so that you can layer them. "If you use lightweight layers then you can add more or take more away depending on the temperature or how your baby feels," Jennifer explains. "The really important thing is that you check how your baby is coping with the heat. Check your baby, not just her hands and feet as these can feel cooler, but check your baby's chest and insider her clothes. If she feels a bit sweaty then you know that she's getting too warm, so you can remove some layers."
"There's no correct amount of layers to use on your baby, because no two blankets are the same and no two babies are the same," says Jennifer. "In summer months use very lightweight sheets, or a low tog rating sleeping bag, and keep checking your baby and if she feels a bit cool you can add either extra layers to your baby or extra sheet or a blanket on top of that."
What should I do in when it's cool?
In winter use a combination of clothes and blankets to in layers to give you more options. "If you baby is in a sleeping bag and it's the biggest tog value but you think your baby's still cold, then you can then add an extra vest, sleeping suit or blanket, and if your baby is in sheets or blankets you can add extra of either," says Jennifer.
When it comes to safe sleeping, you know best. Keep checking your baby and you'll start to learn how to keep her room cool in warm weather, and how many layers she needs to keep her the right temperature in the colder months. "It's so important to check your baby and make sure that your baby is coping ok with whatever the temperature the room is at, says Jennifer.
Real mums tell all
Baby sleep is always a hot topic on social media and in our Forums. Check out what other mums have to say about their experiences on the BabyExpert Facebook page...
“I like to co-sleep, I just put a vest or babygro on depending on temp an a thin blanket over him as our house is always warm and being close to me helps to regulate his temperature anyway,” says Amanda Marie Hodgkinson.
“If I'm particularly worried about baby being the correct temp when asleep I pop my hand down top of sleep suit and vest to see how warm their chest feels. I use a Grobag sleeping bag to keep them warm as can just unzip it if too warm (rather than disturbing by untucking blanket etc) or rest a thin cellular blanket over top if too cold,” says Anmarie Smith.
“I use my baby monitor as it tells me the temp and flashes if to low or high,” says Stacy Gibson.
“We use a gro egg and also the grobag sleeping bags aswell,you can now get sleepsuits that change colour if your baby is too hot or cold,” says Melanie Barnes.
“Sleep suit and a very low tog sleep bag. If temperature too low then a blanket to bring back up to temperature. The monitor in our bedroom used as a baseline guide but the good old fashioned hand on face check is what we normally go by,” says Brian Michael Ayres.
“I use a thermometer and my baby moniter which tell me the temps true of my son room we have thermometer in any room,” says Stacey Hutchins.
