How to choose a sleeping bag for your little one
As your baby grows, transitioning from swaddles to sleeping bags is an important step in creating a safe and restful sleep environment. But with so many options available, how do you know which sleeping bag is right for your baby? This guide covers everything you need to consider to keep your little one cozy and secure all night long.
1. What Is a Baby Sleeping Bag?
A baby sleeping bag is a wearable blanket that allows your baby to sleep safely without the need for loose bedding. It keeps your baby at a consistent temperature and prevents blankets from covering the face, reducing the risk of SIDS (Sudden Infant Death Syndrome).
2. Check the TOG Rating
TOG (Thermal Overall Grade) measures the warmth of a sleeping bag. Choose a TOG rating based on the room temperature:
| Room Temp | TOG Rating | Description |
|---|---|---|
| Above 24°C | 0.2 – 0.5 | Very lightweight, ideal for summer |
| 20–24°C | 1.0 | Mid-weight, perfect for spring/fall |
| 16–20°C | 2.5 | Warm, ideal for cooler nights |
| Below 16°C | 3.5 | Very warm, use in winter |
Tip: Use a room thermometer to track nursery temperature and adjust accordingly.
3. Pick the Right Size
A sleeping bag should fit snugly around the neck and arms but be roomy enough for leg movement. Never size up too much, as babies can slip down into oversized bags.
Typical size guidelines:
0–6 months
6–18 months
18–36 months
Check your baby’s height and weight against the manufacturer’s size chart for the best fit.
4. Choose the Right Fabric
Babies have delicate skin and can easily overheat or get cold. Choose breathable, soft, and skin-friendly materials:
Organic cotton: Gentle and breathable for all seasons
Bamboo: Hypoallergenic and temperature regulating
Fleece or quilted cotton: Warmer options for colder months
Avoid polyester-only fabrics for overnight use unless they’re specifically breathable and safe.
5. Look for Safety Features
Sleeveless design: Prevents overheating and allows freedom of movement
No hoods or cords: To avoid any suffocation hazards
Secure zippers: Look for zipper covers and two-way zippers for easy nighttime diaper changes
Certified standards: Check for OEKO-TEX® or other safety certifications
6. Consider Extra Features
Some sleeping bags come with smart extras like:
Fold-over mittens
Removable sleeves for seasonal use
Travel slots for car seats or prams
Fun prints and glow-in-the-dark zippers
These aren’t essential but can add comfort and convenience to daily routines.
7. Avoid Common Mistakes
Don’t overdress your baby under a sleeping bag—use light sleepwear depending on TOG
Avoid layering multiple sleeping bags
Stop using the sleeping bag when your toddler starts climbing out of the crib
Final Thoughts
A good baby sleeping bag can make bedtime easier, safer, and more restful for everyone. Focus on the right TOG, proper fit, breathable fabrics, and certified safety features to give your baby the cozy sleep they need.
Sleep well, little one—and parents too!
