How Many Layers Does Your Baby Need at Night?

Dressing your baby for sleep does not have to be complicated. The goal is to keep your baby comfortable throughout the night without overheating. Babies are still developing their ability to regulate body temperature, so choosing the right layers is important.

Start with the room temperature
Room temperature matters more than the season. A comfortable sleeping environment for babies is usually between 20–22°C. Always adjust layers based on how warm or cool the room feels.

A simple layering rule
Dress your baby in one more light layer than what you would wear to sleep in the same room. This helps maintain warmth without causing discomfort.

Suggested layers by room temperature
At 24°C and above, a short-sleeve bodysuit or lightweight romper is enough.
Between 20–23°C, a cotton bodysuit with a lightweight sleepsuit works well.
At 16–19°C, use a long-sleeve bodysuit with a warmer sleepsuit and an optional sleep sack.
Below 16°C, choose a long-sleeve bodysuit, a warm sleepsuit, and a well-fitted sleep sack. Avoid loose blankets.

Avoid loose bedding
Loose blankets are not recommended for babies. Sleep sacks or wearable blankets are a safer way to keep your baby warm while allowing natural movement.

How to check your baby’s comfort
Hands and feet often feel cool and are not the best indicators. Instead, gently touch the back of your baby’s neck or chest. Warm and dry skin means your baby is comfortable. If the skin feels hot or sweaty, remove a layer.

Choose breathable fabrics
Lightweight, breathable fabrics such as cotton help regulate body temperature better than heavy or synthetic materials. They reduce the risk of overheating and keep your baby comfortable through the night.

Final note
Every baby is different. Use room temperature, fabric choice, and your baby’s comfort cues as your guide. When in doubt, keep layers simple and breathable for a safer, more restful sleep.
