What is the ideal temprature for my baby overnight?


We are almost through winter and hopefully through the worst of it, but I’m still regularly getting emails and questions about temperature and bedding for babies overnight.

I consistently get asked, what is the ideal temperature in my babies bedroom and what should I be dressing my child in overnight?  I wish that I could give you a simple answer, but different factors can affect the temperature fluctuation how your baby copes with different temperatures and how many layers you should put your baby in, even at the same actual temperature.

All babies are different. Some babies prefer to sleep a little on the cool side, and some (like me) prefer to be a little more on the warm side.

Our goal is to try to dress our baby to comfortable for them!

This means that you need to learn from your baby. You may need to feel your babies chest regularly to make sure that they feel at a comfortable temperature if your baby is sweaty, clammy, or hot to touch you may need to remove layers and if your baby’s chest feels cool to touch you may need to add a layer. Many parents make the mistake of thinking that the baby is cold if their hands or feet feel chilly but often these are not a good way to measure their core temperature. Fingers and toes can often feel cold when the core temperature is perfect, so the best place to gauge your babies cord temperature is on their chest or back.

The way that your baby is sleeping can also help you know if they are a comfortable temperature or too hot or cold. Babies sleeping with their hands up over the head would usually indicate that they’re too hot and trying to cool off. If their hands are relaxed beside the face or beside their body, that tells you that they are a comfortable temperature. If your baby is older and usually sleeps on the side or back they may roll onto their tummy to keep warm. Older babies who are tummy sleepers will roll over onto their back if they are too hot, or they may go into the fetal position or tuck the hands in under their tummy if they are too cold.

You can use a weather app like Weather · by Luni, to check what the outside temperature will drop to overnight each night and use an in-home thermometer to gauge the difference between temperature from inside your home to the outside temperature. After a few days, you will be able to accurately measure how cold your child’s room is going to get overnight and therefore dress your little one accordingly at the beginning of the night.

Other factors like the region that you live in can affect what you dress your child in. For example, if you live in Queensland, the humidity can affect how the temperature feels, and 18° feels a hell of a lot colder to a Queenslander than 18° feels to someone who lives in South Australia. Other factors like whether or not your house has central heating, drafts like a classic Queenslander or insulation / thermal mass like in apartment buildings can affect how the temperature changes overnight. The ideal temperature for sleeping in is recommended between 18 and 22°. Honestly, you need to work out what works for your family by getting to know the above factors.


With all this being said parents still find themselves confused with what to dress their child in and may find themselves with a multitude of different tog rating sleeping bags to choose from each night and through the season which can become very costly and your baby may grow out of before they’ve gotten the best use out of it. I’ve recently come across a Brisbane based company that has really excelled itself in covering all bases with its 365 sleeping bag and X-Tend suit. Their range of sleeping bags and sleepsuits are made from 100% certified organic cotton and are cleverly designed to give maximum usage as your baby grows and keep your baby sleeping safely and comfortably all year round IN THE ONE SUIT!

At first you might think that these sleeping bags are a little expensive, but in reality, these are much cheaper than buying several different togs sleeping bags for different seasons you get the one bag for all seasons saving you time and money. For your not so little ones, The Sleep Company also have their X-Tend sleepsuits the ultimate wearable blanket.
