What TOG Sleeping Bag Does My Baby Need? (Complete Guide for Autumn & Winter)

💤 Understanding TOG Ratings for Baby Sleeping Bags

When it comes to keeping your baby comfortable and safe while they sleep, understanding TOG ratings is essential. TOG (Thermal Overall Grade) measures how much warmth a fabric provides — in other words, how well it traps heat.

A higher TOG means a warmer sleeping bag, ideal for cooler months. A lower TOG means lighter fabric, perfect for summer or warmer nurseries.


🌡️ Baby TOG Guide by Room Temperature

The right TOG sleeping bag depends on the temperature of your baby’s room, not just the season. Use this simple guide to help you choose:

Room Temperature Recommended TOG Suggested Outfit
24°C + (warm rooms) 0.2 – 0.5 TOG Short-sleeve bodysuit
21–23°C 1.0 TOG Long-sleeve bodysuit or thin sleepsuit
18–20°C 2.5 TOG Long-sleeve sleepsuit or vest + sleepsuit
15–17°C 3.5 TOG Warm sleepsuit or layers as needed

💡 Tip: Always check the room temperature, not outdoor temperature. Use a reliable nursery thermometer to guide you.


🍂 Choosing the Right Sleeping Bag for Autumn

Autumn can be tricky — days may feel mild but nights turn chilly. A 2.5 TOG baby sleeping bag is ideal for this time of year. It keeps your baby snug through cooler nights while preventing overheating during warmer evenings.

If your nursery tends to stay around 18–20°C, this TOG range offers the perfect balance of comfort and safety.


❄️ What About Winter?

When temperatures drop below 17°C, it’s time to consider a 3.5 TOG winter baby sleeping bag. This thicker style provides extra insulation for cold nights — no need for loose blankets that can pose a safety risk.

Pair it with a long-sleeved sleepsuit or vest, and your baby will stay warm and cozy throughout the night.

⚠️ Safety note: Avoid overdressing your baby. Signs of overheating include sweating, flushed cheeks, or damp hair.


👶 Why Sleeping Bags Are Better Than Blankets

Sleeping bags maintain a consistent baby sleep temperature all night long. They prevent your little one from kicking off covers and waking up cold — promoting longer, safer sleep.

🧺 Caring for Your Baby’s Sleeping Bag

  • Wash at 40°C with gentle detergent

  • Tumble dry on low or line dry

  • Avoid fabric softeners (they can affect breathability)

  • Always check the TOG label before each season change
