How to Dress Your Baby for Sleep in Any Temperature

Knowing how to dress baby for sleep can help your child stay safe, warm, and comfortable all night long. Babies are sensitive to temperature changes, and the wrong attire can disturb their rest. Choosing breathable fabrics and layering appropriately ensures they neither overheat nor get too cold.
Why Dressing Matters for Baby Sleep
Keep Sleep Safe and Comfortable
Your baby’s sleepwear must align with the room temperature. Babies can’t regulate their body temperature like adults. So, the right clothes protect them from overheating or chilling.
- Choose one extra layer than what you wear.
- Use soft, breathable materials like cotton.
- Avoid beanies and loose-fitting nightgowns.
Maintain the Right Temperature
The ideal room temperature for babies is around 69°F (20.5°C). A cooler room lowers the risk of SIDS. If your baby sweats or wakes often, they might be too warm. Feel their back or tummy to check their body heat—not their hands or feet.

Light and Airy Clothing
Hot weather requires breathable, light clothes to avoid overheating.
- Dress your baby in a sleeveless onesie or singlet with a diaper.
- Use cotton or muslin fabrics.
- Keep fans on, away from your baby.
Signs of overheating include sweating, flushed skin, and fast breathing. If you notice these, remove a layer.
How to Dress a Baby in Winter
Keep Them Warm Without Overheating

Cold nights need more layers, but not too many.
- Use a full suit or long-sleeve onesie with footed pajamas.
- Avoid hats or beanies at bedtime.
- Try a sleep sack rated 2 TOG for extra warmth.
Don’t use electric blankets. Keep the door slightly open for ventilation.
