Introduction
Ever stood over your baby’s crib, wondering if they’re too warm or too chilly? You’re not alone. I remember pacing around our room at 2 a.m., checking the thermostat and Googling “23 degrees baby sleep” with one eye open.
Dressing your baby right for sleep isn’t just about comfort—it’s about safety and peace of mind. If your room sits at 23°C, you might be asking yourself how to dress baby for sleep at 23 degrees without overthinking it. This guide breaks
it down simply, with gentle, expert-backed tips to help your little one sleep safe and sound. Let’s make bedtime one less thing to worry about.

Section 1: Understanding the 23°C Room Temperature
Let’s talk about what 23°C really means for baby sleep. It’s on the warmer side. Not hot, but warm enough that too many layers can make your baby overheat. I used to think 23 felt fine—but babies feel heat more than we do. Their little bodies can’t cool down as fast.
Experts say the best sleep temperature for babies is between 16°C and 20°C. So, 23°C is a bit warm for sleep. That’s why you need to dress your baby in light clothes. If you’ve been wondering what should baby sleep in at 23 degrees?—you’re in the right place. Let’s keep it cool, simple, and safe.

Section 2: What Should a Baby Sleep In at 23 Degrees?
The room is 23°C. It feels warm, but not hot. So, what should baby sleep in at 23 degrees?
Here’s the short answer: keep it light.
At this temp, your baby doesn’t need much. One or two thin layers are enough. Here’s a quick list:
- A short-sleeved bodysuit
- A light cotton sleepsuit
- A 0.5 to 1.0 tog sleeping bag
That’s all. No hats. No thick socks. No extra blankets. Too many layers can make your baby too warm, and that’s not safe.
If you’re asking, “What should a baby sleep in at 23 degrees?”—this is your guide. Simple. Comfy. Safe.
Still not sure? Feel the back of their neck. If it’s warm, they’re fine. If it’s sweaty, take off a layer.
When it comes to 23 degrees baby sleep, less is more.
Section 3: Baby Sleep Clothes for 23 Degrees
When your room is 23°C, light clothes are best. Pick soft, airy fabrics like cotton or bamboo. They help your baby stay cool and dry. I like organic blends too—they feel smooth and gentle.
Skip thick stuff like fleece. It holds heat and can make your baby too warm. No big blankets either. I tried that once, and my baby got all sweaty and fussy. For 23 degrees baby sleep clothes, think light and breezy.
Wondering how to check if your baby is too hot or cold? Just feel the back of their neck. Warm is fine. If it’s sweaty, take off a layer. If it’s cool, add a light one.
At 23 degrees, what should baby sleep in? Something simple. A short-sleeved bodysuit and a light sleep sack usually do the trick. Keep it easy. Keep it safe.

Section 4: Is a Sleeping Bag Good for 23°C?
A sleeping bag can be great for 23°C, but it’s important to pick the right one. Baby sleeping bags come with different tog ratings. Togs measure how thick or thin the bag is. The higher the tog, the warmer it keeps your baby.
For 23 degrees baby sleep, choose a 0.5 tog or 1.0 tog sleeping bag. A 0.5 tog is light and perfect for warmer nights. A 1.0 tog adds a little more warmth but still lets your baby stay cool. I’ve used both and loved them.
Don’t go for a 2.5 tog at this temperature. It’s too thick and can make your baby too hot. I learned this after a sweaty, restless night. Trust me, less is more.
If you’re looking for safe and comfy options, try Love to Dream, Grobag (Tommee Tippee), or ErgoPouch. They list the tog ratings clearly, making it easier to choose the right one.
So, yes—a sleeping bag
Section 5: Tips for Safe Baby Sleep at 23 Degrees
When it comes to 23 degrees baby sleep, simple is best. I used to worry. I’d put on too many layers, tuck in a cute blanket, even try a little hat. It felt right—but it wasn’t safe.
Tip one: skip the extras. No hats. No mittens. No loose blankets. These things can make your baby too warm or pose a risk. Babies cool off through their heads, so a hat can trap heat. Blankets might shift during sleep, and that’s not safe.

Keep the crib plain. A firm mattress with a fitted sheet is all you need. I once tried using a soft blanket to help my baby sleep better. But it only made her sweaty and fussy. Now I use a light sleeping bag and soft cotton clothes. It works so much better.
Use your hands to check. Wondering if your baby is too hot or too cold? Touch the back of their neck or chest. Warm is good. If it’s sweaty, take off a layer. If it’s cool, add a light one. Hands and feet can feel cold even when your baby is fine.
Every baby is a bit different. But these signs help. Now, when I think about what should baby sleep in 23 degrees, I know the answer: just a few light layers and a safe setup.
23 degrees Celsius baby sleep can still be safe and comfy. Trust your gut. Keep it light. And let your baby sleep easy.
Section 6: Real Parent Tip: What I Do When It’s 23°C at Night
When the room is 23°C, I keep things light. The first time I saw that number on the baby monitor, I wasn’t sure what to do. I looked up “23 degrees baby sleep” and read a dozen blogs. I still felt confused.
So I tried a short-sleeved bodysuit and a light 0.5 tog sleep sack. It worked. My baby stayed cool and slept well. If her neck feels warm but not sweaty, I know I got it right.
My friend uses a thin cotton sleepsuit instead. Her baby gets cold more easily. That’s the thing—what should baby sleep in at 23 degrees? It depends. Every baby is different.
So here’s what I’ve learned: Start with less. Feel your baby’s neck. Add or take off a layer as needed. 23 degrees baby sleep isn’t one-size-fits-all. But with soft layers and a little trial and error, you’ll find what works.
Conclusion: Keep It Simple and Comfortable
If the room is 23°C, don’t stress. For 23 degrees baby sleep, go light. A soft bodysuit and a thin sleep sack are often enough. Keep it cool and easy.
I used to worry about what to put on my baby. I’d ask myself, what should baby sleep in 23 degrees? But once I stopped adding extra layers, sleep got better—for both of us.
Trust your gut. Feel the back of your baby’s neck. Warm is fine. Sweaty? Take off a layer. Cool? Add something light. That’s how I check every night.
Your baby’s sleep at 23°C doesn’t need to be hard. Use soft clothes. Pick breathable fabric. Skip the extras. That’s it.

I found this guide really helpful, especially the part about checking the back of the baby’s neck to see if they’re too warm or cold. It’s such a simple tip, but it makes so much sense. I’ve always worried about over-layering, and now I feel more confident about dressing my baby for sleep. The suggestion to use light fabrics like cotton or bamboo is great—I’ll definitely look for those. I’m curious, though, how do you handle temperature changes during the night? Do you adjust the layers if the room gets cooler? Also, what’s your take on sleep sacks versus swaddles at this temperature? I’d love to hear your experience!
