Learn when and how to use the Cocoon Swaddle Bag 1.0 TOG, from room temperature checks to arms-in vs arms-out swaddling and fit checks.
Quick answer
Use the Cocoon Swaddle Bag 1.0 TOG when your baby's room is warm and you need a light layer that can be worn arms-in, hands-up, or arms-out. Start with arms-in for the startle reflex, then switch to arms-out when your baby shows signs of rolling.
Why 1.0 TOG suits warmer rooms and how to judge the temperature
The 1.0 TOG rating is a light warmth level, so it fits when the nursery is warm rather than cool. Rather than guessing, check the actual room temperature with a thermometer and dress your baby in a simple base layer underneath. If the room is cool, this bag alone won't add enough warmth; if it's hot, even a light bag may be too much. The right TOG depends on your baby's room, not the season on the calendar.
Arms-in vs arms-out: when to switch
The startle reflex is strongest in the early months, and arms-in or hands-up positions can help your baby feel secure. As the reflex fades and your baby begins to roll, arms-out becomes safer because it allows free movement. There is no fixed age for the switch; watch your baby's cues and upper body strength. If you are unsure, ask your pediatrician or health visitor.
Fit matters more than you think
A swaddle that is too loose can ride up over the face, while one that is too tight can restrict hip movement. The Cocoon Swaddle Bag comes in a range of sizes and colours, so choose the size that matches your baby's weight and length. Always check the fit around the neck and arms before each use, and stop using a size that has become too small.
How to use the Cocoon Swaddle Bag 1.0 TOG step by step
- Check the room temperature: Use a thermometer to confirm the nursery is warm (typically 21–23°C is comfortable for lightly dressed babies, but always follow your baby's cues). If the room is cooler, choose a higher TOG; if it's hotter, consider a lower TOG or lighter clothing. A thermometer takes the guesswork out of TOG choice.
- Dress your baby in a base layer: Put your baby in a simple bodysuit or light sleepsuit—no thick blankets or extra layers inside the bag. The 1.0 TOG bag provides the warmth, so overdressing underneath can cause overheating. Keep the base layer light to match the 1.0 TOG rating.
- Choose the wearing position: Start with arms-in or hands-up if your baby still has a strong startle reflex. Switch to arms-out once your baby shows signs of rolling or prefers free arms. Always place your baby on their back for sleep. Arms-out is the safe choice as soon as rolling begins.
- Fasten and check the fit: Zip or fasten the bag according to the instructions, then check that there is room for two fingers at the neck and that the bag doesn't ride up over the face. Make sure the legs can move freely and the hips can fall into a natural frog position. A correct fit allows hip movement and keeps the neckline secure.
- Watch for signs of overheating: Feel your baby's chest or back—if it's clammy or sweaty, remove a layer. Common mistake: relying on hands or feet, which are often cooler than the core. Check the chest, not the hands, to judge warmth.
- Know when to stop swaddling: Stop using the arms-in position as soon as your baby attempts to roll, even if they haven't mastered it. Transition to arms-out or a sleeping bag. If your baby resists, try one arm out first. Rolling is the signal to move to arms-out—don't wait for full rolling.
