Is Your Baby Cold at Night? Signs, Myths, and How to Keep Them Warm Safely

Winter nights can be tricky for babies. Parents often worry if their little one is warm enough, but here’s the truth: you can’t judge your baby’s temperature by touching their hands.

Why? Because a baby’s circulation system is still immature, so their hands (and feet) are often cooler than the rest of their body. That doesn’t necessarily mean they are cold.

Instead, here are more reliable signs to check if your baby might be chilly at night and safe ways to keep them cozy without overheating or creating risks.

 Want a quick breakdown? I also shared these tips in my Instagram reel.

Signs Your Baby Might Be Cold at Night

1. Curled Up Sleeping Position

Many babies naturally curl up, but if your baby usually sleeps flat and suddenly starts curling into a tight ball, it’s often their body’s way of conserving heat just like adults do when we feel cold.

2. Cold Chest or Back of Neck

Checking your baby’s chest or the back of their neck is a much more accurate way to judge core body temperature. If these areas feel cool to the touch, your baby might need an extra layer.

3. Early Morning Wakings

If your baby normally sleeps well but suddenly starts waking in the early morning hours during winter, temperature drops could be the reason.

4. Diaper Leaking

Yes, even diaper leaks can signal cold nights! Just like adults, babies may pee more when their bodies are cold, leading to unexpected leaks overnight.

Safe Strategies to Keep Your Baby Warm

❌ Avoid Heavy Blankets
Blankets can be a suffocation hazard, especially for babies under one year old.

❌ Skip the Night Cap
Covering your baby’s head while sleeping can cause overheating and is not safe.

✅ Dress in Layers
Use thicker sleepwear or dress your baby in multiple light layers. The air trapped between layers adds insulation.

✅ Use a Quilted Sleep Sack
A baby sleep sack (also known as a wearable blanket) is one of my top recommendations. Look for a quilted version with a TOG rating of 2.0 or higher in colder months. If you can’t find one, double up with two lighter sacks and dress your baby underneath in warm layers.

✅ Adjust Room Temperature
If the nursery is too cold, use a safe radiator or blower. Pair it with a humidifier to prevent the air from getting too dry.

Final Thoughts

Keeping your baby warm at night is about balance avoiding both chills and overheating. By focusing on reliable temperature checks and safe sleep practices, you’ll help your little one stay comfortable through the winter months.

And remember, small adjustments like switching to a quilted sleep sack or dressing in layers can make a big difference for better, longer stretches of sleep.
