What should your baby sleep in when the room is 24–25°C?
A room temperature of 24–25°C does not seem extremely warm at first, yet it is easy to feel unsure: will your little one get too hot? Or, on the other hand, could they get chilly by the early hours? These are completely real concerns, and almost every parent comes across them. This is exactly where we would like to help: with clear, simple guidance so you can feel more confident deciding what your baby should sleep in at this temperature, in a way that helps them rest well and gives you peace of mind too.
This is the kind of temperature where lighter clothing already feels pleasant for us as adults. With babies, however, we usually need to allow for one extra layer. So what is worth paying attention to, how does your baby’s body respond, and what can help make their sleep truly comfortable?
The short answer:
If the room is 24–25°C, a short-sleeved bodysuit and a lightweight sleepsuit with socks, or a short-sleeved bodysuit with a 0.5 TOG sleeping bag, is usually the best choice. At this temperature, the aim is to make sure your baby does not overheat, but does not get cold either. Light, breathable layers are the easiest way to achieve this.
Why is the right sleepwear important in a warm room?
At first, 24–25°C may seem ideal, but for babies it is already a more sensitive range. Newborns and young babies are not yet able to effectively regulate their body temperature, which means they can overheat more easily.
This is also why a warmer environment is often recommended for them in the first weeks. Based on LiaaBébé’s experience, the material you dress your baby in matters especially at this stage, because a well-chosen fabric can almost help regulate the surrounding warmth for you.
The “one extra layer” rule, but not in every case
You have probably heard that babies should wear one more layer than we would feel comfortable in. This is a good starting point, but it is not something to follow blindly.
Some babies sweat more easily, while others tend to feel the cold. It also matters how much they move during the night, and whether the room temperature changes towards the morning. It is better to watch the signs and adjust their clothing accordingly.
Check whether your baby feels comfortable
A question that often comes up is: how do I know whether my baby is dressed properly? The simplest method is to touch the back of their neck or their chest.
If their skin feels warm and dry, they are very likely comfortable. If they are sweaty or damp, they are too warm. If they feel cool, they may be cold. Hands and feet are not always reliable indicators, as they are often cooler.
What can disturb sleep at this temperature?
Although 24–25°C feels pleasant, several small factors can affect the night. One of these is temperature fluctuation: it may still be warmer in the evening, while the air can cool down towards the early morning.
Changes in humidity also play a part, as does the fact that a baby can easily kick off their blanket. They may also sweat. Together, these can be enough to cause one or two night wakings.
Humidity has a big impact on your baby’s comfort. If the air is too dry, it can irritate the airways. If it is too high, the room can feel heavy and muggy. It is worth aiming for around 60–70%, as babies tend to feel most comfortable within this range.
Sleeping bag or blanket?
This is one of the most common dilemmas, and it is completely understandable. We love a baby blanket just as much as a sleeping bag, but the downside is that your baby can easily kick it off, pull it over their face, or bunch it up underneath them.
A sleeping bag, on the other hand, provides a stable feeling of warmth. It does not slip, it does not cover the face, and there is no need to adjust it again and again during the night. LiaaBébé recommends a 0.5 TOG sleeping bag as an ideal choice at this temperature.
It is worth talking about fabric choice too
It is not only the number of layers that matters, but also what those layers are made from. A poorly breathable fabric can easily make your baby too warm, even if you have not overdressed them.
Bamboo fibre, for example, works particularly well in warmer environments too. Based on LiaaBébé’s experience, it helps wick away moisture and provides a pleasant, dry feeling throughout the night. Your baby’s skin is less likely to become damp or irritated, and heat rash is less likely to appear, which makes it one of the best textile choices for children with allergy-prone skin.
Practical dressing tips for 24–25°C
At this temperature, a short-sleeved bodysuit and a lightweight sleepsuit often work well together. If you prefer using a sleeping bag, then a 0.5 TOG thickness can be a perfect choice. For older children, lightweight pyjamas may also be suitable, or even a sleeping bag with feet if they do not reliably keep a blanket on yet.
With LiaaBébé’s recommendations, you can choose pieces designed specifically around your baby’s comfort. They are soft, stretchy, and do not restrict movement, which is especially important during sleep.
One of the great advantages of bamboo fabric is that it adapts to temperature. It does not overheat your baby, yet still feels pleasantly cosy. Even better, it keeps its quality over time, so it really is a practical choice in the long run.
Frequently asked questions
Can a baby sleep in just a bodysuit at 25°C?
Yes, in some cases this may be enough, provided the baby is not a newborn, does not tend to feel cold, and the fabric is breathable.
Do I need to get up at night to check whether my baby is too hot or too cold?
Not regularly, but at the beginning it is worth checking once or twice to see whether you have chosen the right sleepwear.
Which is better: a sleeping bag or pyjamas?
For smaller babies, a sleeping bag is usually the better option. For older children, pyjamas can also work well if they do not kick off their blanket.
Parent reviews
Based on feedback, it is clear that most mums feel more confident about dressing their baby once they find the right balance between suitable layering and breathable fabrics. Many have highlighted that lighter bamboo-based clothing and the use of a sleeping bag significantly reduced the number of night wakings. Several parents said they had previously felt unsure about whether they were over- or under-dressing their baby, but once they started paying closer attention to temperature and materials, the nights became much calmer.
A recurring point in the feedback was that the baby’s comfort visibly improved, with less sweating and less restlessness caused by feeling cold. Overall, parents’ experiences confirm that the right sleepwear and thoughtful fabric choice can bring calmer sleep not only for the baby, but for the whole family.
In a room of 24–25°C, light, breathable clothing is the best choice for your baby’s sleep. If you pay attention to your baby’s cues, the right materials, and the sleeping environment, nights can become much more peaceful.
Based on LiaaBébé’s experience, high-quality natural materials can help a great deal, and ultimately this is what can make your little one’s sleep truly comfortable.
