Choosing the right baby sleeping bag is essential for safe and restful sleep. With so many options available, it can be tricky to know where to start. That’s why we’ve created this easy-to-follow checklist to help you find the perfect sleeping bag for your baby or toddler.
✔ 1. Choose the Right Type
➤ Swaddle bags – A 2-in-1 option for newborns that gently swaddles arms and converts into a standard baby sleeping bag when your baby is ready.
➤ Standard baby sleeping bags – Ideal for newborns and younger babies who aren’t walking yet. They help regulate temperature and prevent blankets from being kicked off.
➤ Sleeping bags with feet – Perfect for active toddlers. These allow little ones to move freely, crawl, and walk safely while staying cosy.
Slumbersac’s sleeping bags and sleeping bags with feet are available from newborn to 10 years.
✔ 2. Check the TOG Rating
The TOG value indicates how warm the sleeping bag is. Use this TOG guide based on room temperature:
➤ 0.5 TOG – Hot weather (over 24°C)
➤ 1.0 TOG – Mild spring/summer nights (21–24°C)
➤ 2.5 TOG – All-year-round use (15–21°C)
➤ 3.5 TOG – Cold nights and winter (below 18°C)
Always match the TOG to the room temperature, not the season. All Slumbersac sleeping bags are tested to ensure TOG accuracy.
✔ 3. Pick the Right Size
The baby sleeping bag should be snug around the neck and arms, but roomy enough for legs to move freely.
➤ Measure your child from shoulders to feet and add approx. 10cm for comfort
➤ Ensure the head can’t slip through the neck opening
➤ For bags with feet, choose a size that corresponds with your child’s height
Refer to our Sleeping Bag Size Guide for help choosing the right fit.
✔ 4. Prioritise Safe Design Features
For peace of mind, make sure your baby sleeping bag includes:
➤ A fitted neck and armholes to prevent slipping
➤ No loose fabrics or drawstrings
➤ Conforms to British or European Safety Standards
➤ Zip guards and safety covers to protect your baby's skin
✔ 5. Select the Right Material
The fabric and lining can affect both comfort and safety.
➤ Cotton outer and lining – Soft, breathable, and gentle on sensitive skin. Cotton is durable, easy to wash, and ideal for everyday use.
➤ Polyester filling – Lightweight, warm, and quick-drying. It provides excellent insulation without adding bulk and helps maintain a consistent temperature without overheating.
All Slumbersac sleeping bags are made with OEKO-TEX 100 certified fabrics – free from harmful substances and safe for even the most delicate skin.
✔ 6. Look for Practical Details
➤ Zips or poppers for easy nappy changes
➤ Adjustable arm poppers for a safe, secure fit
➤ Zip chin guards to protect baby's sensitive skin from being pinched
➤ Machine washable at 60 degrees and tumble-dry safe for everyday ease
➤ Foldable feet covers for flexibility (in sleeping bags with feet)
✔ 7. Choose a Child-Friendly Design
➤ Bright colours and playful patterns can encourage visual development
➤ Fun characters and themed prints make bedtime more enjoyable
Slumbersac’s fun character prints are designed to support emotional well-being and make sleep something to look forward to.
✔ 8. Buy from a Trusted Brand
Look for a brand that:
➤ Has years of experience in baby sleepwear
➤ Prioritises safety and comfort
➤ Offers helpful tools like filters, size guides, and TOG calculators
➤ Has great customer reviews and award-winning products
Slumbersac has been trusted by parents for over 15 years, combining quality materials with thoughtful designs.
Every baby is different
Some love the freedom of a sleeping bag with feet, while others prefer the snugness of a traditional sleep bag. If you’re unsure, our handy filter tool lets you search by TOG, size, colour, and design to find the perfect fit for your little one.
