Quick answer
For infants 1-6 months, choose a baby sleeping bag with a snug fit around the chest and arms, no loose bedding, and a TOG rating appropriate for your room temperature. Our top pick is the Baby Sleeping Bag (1-6 M).
Why a sleeping bag beats loose blankets
Loose blankets can cover a baby's face and increase the risk of suffocation. A wearable baby sleeping bag stays in place, keeps your infant warm without overheating, and reduces the chance of the startle reflex waking them up. For the 1-6 month stage, a well-fitted sleep sack is the safest alternative to swaddling once your baby starts rolling.
Understanding TOG ratings and room temperature
TOG measures thermal insulation. A 0.5 TOG bag suits warm rooms (24-27°C / 75-80°F), 1.0 TOG works for moderate rooms (20-24°C / 68-75°F), and 2.5 TOG is best for cooler rooms (16-20°C / 61-68°F). Always check the room temperature with a thermometer and dress your baby in a short-sleeve onesie under the bag—no extra hats or blankets.
Decision rules for a safe fit
- Check the neck and arm openings: The opening should be snug enough that you cannot pull the bag over your baby's chin. Two fingers should fit between the bag and your baby's chest. If the opening gaps, choose a smaller size or a different brand.
- Measure your baby's length against the bag: The bag should end at or below the baby's shoulders when arms are inside. For 1-6 month bags, the bottom should not extend past the baby's toes when legs are straight.
- Choose the right TOG for your nursery: Use a room thermometer. For 20-24°C (68-75°F), a 1.0 TOG bag is ideal. Dress baby in a short-sleeve onesie under the bag—no extra layers inside. Check the bag's label for TOG rating; if not listed, assume 1.0 TOG and adjust room temperature.
- Stop using when baby shows signs of rolling: Once your baby can roll from back to tummy, switch to a sleep sack that leaves arms free. The Baby Sleeping Bag (1-6 M) is designed for this stage, but always supervise transitions. Replace with an arms-free sleep sack once rolling begins.
