How to Regulate Your Baby’s Body Temperature All Year Round

Your baby can’t yet regulate their body temperature like adults — that means it’s up to you to help them stay cozy in winter and cool in summer. Keeping your baby at the right temperature helps with better sleep, comfort, and overall health.

Here’s how to manage your baby’s body temperature safely throughout the year:

1. Feel, Don’t Guess.
Touch the back of your baby’s neck or chest — that’s the best indicator of whether they’re too hot or too cold (not their hands or feet!).

2. Dress by the “One Layer Rule.”
In general, dress your baby in one more layer than what you’re comfortable wearing.

3. For Winter:
Use soft, breathable layers — cotton bodysuits under fleece or knitwear. Avoid overheating by checking for sweat or flushed skin.

4. For Summer:
Choose light, loose clothing made from natural fibers. Keep rooms between 22–25°C and avoid direct sunlight exposure.

5. During Sleep:
Use a sleep sack or swaddle to maintain warmth without loose blankets. Babies sleep best when their environment feels stable and gentle.
