A baby sleeping bag is an essential item for safe and comfortable sleep. Unlike loose blankets, which can pose a SIDS (Sudden Infant Death Syndrome) risk, a sleeping bag keeps your baby warm, secure, and safe throughout the night. But with so many options available, how do you choose the right one for your baby?
In this guide, we’ll cover everything you need to know about choosing the perfect sleeping bag—from TOG ratings to fabric choices and sizing.
1. Why Use a Baby Sleeping Bag?
A baby sleeping bag (also called a wearable blanket) is a safe and cozy alternative to loose blankets. It provides:
✔️ Even warmth – No risk of blankets being kicked off, ensuring baby stays warm all night.
✔️ Safe sleep positioning – Reduces the risk of suffocation or getting tangled in loose bedding.
✔️ Easier nighttime changes – Many sleeping bags have two-way zippers for quick diaper changes.
✔️ Better sleep for parents and baby – Keeps baby snug, reducing unnecessary wake-ups.
2. Choosing the Right TOG Rating
The TOG (Thermal Overall Grade) rating measures the warmth of the sleeping bag. The higher the TOG, the warmer the sleeping bag.
TOG Rating Guide:
| TOG Rating | Best for Room Temperature | Season |
|---|---|---|
| 0.2 TOG | 24°C+ (75°F+) | Hot summer nights ☀️ |
| 1.0 TOG | 20-24°C (68-75°F) | Mild weather 🌤 |
| 2.5 TOG | 16-20°C (61-68°F) | Cooler nights 🍂 |
| 3.5 TOG | Below 16°C (61°F) | Cold winter nights ❄️ |
💡 Tip: Always check your baby’s room temperature before choosing a TOG level!
3. What Fabric is Best for a Baby Sleeping Bag?
Since babies have sensitive skin, choosing the right fabric is crucial.
✔️ 100% Cotton – Soft, breathable, and safe for delicate skin (Babivi’s sleeping bags are made of this!).
✔️ Organic Cotton – Free from harmful chemicals and ideal for babies with eczema or allergies.
✔️ Bamboo Fabric – Lightweight, moisture-wicking, and super soft, but often pricier.
✔️ Avoid Synthetic Fabrics – Polyester can cause overheating and irritation.
💡 Tip: Always choose breathable, natural fabrics to prevent overheating!
4. What Size Sleeping Bag Should You Choose?
A sleeping bag should be snug around the chest and arms but loose around the legs to allow for movement.
Sleeping Bag Size Guide
| Baby’s Age | Recommended Sleeping Bag Length |
|---|---|
| Newborn - 6 Months | 60-70 cm (23-27 inches) |
| 6-18 Months | 70-90 cm (27-35 inches) |
| 18-36 Months | 90-110 cm (35-43 inches) |
💡 Tip: If your baby is between sizes, choose the smaller size to prevent slipping inside the bag.
5. Sleeveless or With Sleeves?
✔️ Sleeveless Sleeping Bags – Better for temperature regulation and reducing overheating.
✔️ Long-Sleeved Sleeping Bags – Great for winter but make sure they are not too thick.
💡 Tip: If you choose a sleeveless sleeping bag, dress your baby in a long-sleeved onesie for extra warmth!
6. Zippers vs. Buttons – Which is Better?
✔️ Two-Way Zippers – Makes diaper changes quick and easy without fully removing the bag.
✔️ Side Zippers with Snap Buttons – Prevents baby from escaping but can be trickier during nighttime changes.
💡 Tip: Always check for a zipper cover at the top to prevent irritation on baby’s chin!
7. How to Dress Your Baby Under a Sleeping Bag
Your baby’s clothing layers depend on the TOG rating and room temperature.
Dressing Guide for Sleeping Bags
| Room Temperature | TOG Rating | Baby’s Outfit |
|---|---|---|
| 24°C+ (75°F+) | 0.2 TOG | Short-sleeve onesie |
| 20-24°C (68-75°F) | 1.0 TOG | Long-sleeve onesie & pants |
| 16-20°C (61-68°F) | 2.5 TOG | Long-sleeve onesie & sleepsuit |
| Below 16°C (61°F) | 3.5 TOG | Thick onesie & sleepsuit |
💡 Tip: Feel the back of baby’s neck—if it’s sweaty, they’re overdressed!
