Learn how to layer the ergoPouch Grows with You 2.5 TOG Bundle for safe, warm winter sleep. Step-by-step guide with common mistakes to avoid.
Quick answer
For winter sleep with the Grows with You 2.5 TOG Bundle, dress your baby in a long-sleeve bodysuit and footed pajamas, then use the Cocoon Swaddle Bag for newborns and transition to the Sleeping Bag as they grow. Always check your baby's neck or chest for warmth.
Why the 2.5 TOG Bundle suits winter
The 2.5 TOG rating is designed for cooler room temperatures (around 61-68°F / 16-20°C). This makes the bundle ideal for winter nights when your heating might be lower or the room runs cool.
The bundle includes two pieces: a Cocoon Swaddle Bag and a Sleeping Bag, both in 2.5 TOG. This lets you start with swaddling for newborns and move to a sleeping bag as your baby grows—without buying separate items.
Layering correctly is key: the TOG rating of the sleepwear combined with the sleep sack should match the room temperature. The bundle's 2.5 TOG provides the main insulation, so base layers should be light.
Know when to switch from swaddle to sleeping bag
The Cocoon Swaddle Bag is for newborns who still have the startle reflex. Once your baby starts rolling over (usually around 3-4 months), switch to the Sleeping Bag to reduce the risk of suffocation.
The Sleeping Bag has a wider fit and allows leg movement, which is safer for older babies. It also has a longer usable life, so you get more value from the bundle.
If you're unsure whether your baby is ready to transition, look for signs of rolling or increased fussiness when swaddled. Always prioritize safety over habit.
How to layer for winter sleep
- Check the room temperature: Use a room thermometer to ensure the nursery is between 61-68°F (16-20°C). This is the ideal range for a 2.5 TOG sleep sack. If the room is warmer, consider a lighter TOG or fewer layers. Never rely on feel alone—always verify the temperature with a thermometer.
- Dress your baby in a base layer: For newborns, put on a long-sleeve bodysuit and footed pajamas under the Cocoon Swaddle Bag. For older babies, use the same base under the Sleeping Bag. Avoid bulky or fleece layers, as they can cause overheating. If your baby's neck or chest feels sweaty, remove a layer—don't wait for a rash.
- Secure the swaddle or sleeping bag correctly: For the Cocoon Swaddle Bag, place your baby's arms inside the swaddle wings and zip up. For the Sleeping Bag, ensure the arm openings fit snugly but not tight. The bag should be loose around the legs to allow natural movement. Make sure the zip is fully covered and the bag fits without bunching—never leave loose fabric near the face.
- Monitor your baby through the night: Check your baby's temperature by feeling the back of the neck or chest. If it's warm and dry, the layering is correct. If it's hot or sweaty, remove a layer. Also ensure your baby's head is uncovered—never use a hat indoors. Red cheeks or rapid breathing can signal overheating; act quickly if you notice these signs.
