Learn how to pick a safe, warm baby sleeping bag. Check tog rating, size, and materials like organic cotton. Includes decision rules and fit guidance.
Quick answer
Choose a baby sleeping bag that fits your child's weight and age, has the right tog rating for the room temperature, and uses safe, breathable materials like organic cotton.
Why tog rating matters more than thickness
A sleeping bag's tog rating tells you its thermal insulation. A 1.0 tog bag works for warm rooms (24-27°C), while a 2.5 tog bag suits cooler rooms (16-20°C). Never guess by feel; always check the label.
Size and fit: the safety factor
A bag that's too big lets your baby slip down inside, risking suffocation. Too small restricts movement and can cause overheating. Match the bag to your baby's weight, not just age.
Material choices: breathability and comfort
Organic cotton outer layers are gentle on sensitive skin and help regulate temperature. Recycled polyester wadding offers warmth without extra weight. Avoid synthetic linings that trap heat.
Decision rules for choosing a baby sleeping bag
- Check the tog rating: Use a 0.5 tog bag for summer (27°C+), 1.0 tog for warm rooms (24-27°C), 2.5 tog for cooler rooms (16-20°C). Never exceed 3.5 tog.
- Match size to weight: Most bags list a weight range (e.g., 4-8 kg, 8-12 kg). Choose the range that fits your baby's current weight, not their age. Weigh your baby before buying.
- Check the zipper and fastenings: Look for a 2-way zipper along one side for easy diaper changes. Snap buttons at the shoulders and armhole prevent the bag from riding up. Test the zipper before first use.
