Quick answer
For newborns who still have a strong startle reflex and need a snug, contained feel, the Cocoon Swaddle Bag 0.2 TOG is the better choice. Once your baby starts rolling or prefers arms-free sleep, the Sleeping Bag 3.5 TOG (for cooler rooms) or a lighter TOG sleeping bag becomes the safer and more practical option.
When to use each product
The Cocoon Swaddle Bag is designed specifically for the newborn stage when babies benefit from gentle containment. Its three-in-one design lets you keep arms in, hands up, or arms out, so you can gradually adjust as your baby’s startle reflex fades. The 0.2 TOG rating means it’s a lightweight layer best suited for warmer climates or summer months.
The Sleeping Bag 3.5 TOG, on the other hand, is built for arms-out sleepers, typically from around 3 months of age. Its sleeved design keeps the body warm while allowing free arm movement. The 3.5 TOG warmth rating makes it ideal for cooler room temperatures or colder seasons.
The key trade-off is warmth and age suitability: the Cocoon Swaddle Bag is lighter and contains the arms, while the Sleeping Bag provides more insulation and freedom of movement. Choose based on your baby’s developmental stage, room temperature, and sleep preferences.
Cocoon Swaddle Bag vs Sleeping Bag: trade-offs
- Startle reflex containment: Cocoon Swaddle Bag offers three arm positions (arms in, hands up, arms out) to gradually reduce swaddling as the reflex fades.
