Frequently Asked Questions
How do I know if my baby is overheating in a swaddle or sleep sack?
Check the back of the neck — if it’s hot or damp, your baby may be overheating. Other signs include sweating, flushed cheeks, rapid breathing, or unusually restless sleep. Hands and feet being warm or cool aren’t reliable indicators. If you suspect overheating, remove a layer, switch to a lighter swaddle or cotton-only option, and lower room temperature if needed.
Can I swaddle my baby in summer without overheating?
Yes — choose breathable, lightweight fabrics (100% cotton or muslin), arms-only or low-fabric swaddle styles, and avoid hats or extra blankets. Use a lower-TOG sleep sack for additional warmth control, and keep the nursery in the recommended range of about 68–72°F (20–22°C). Monitor your baby’s neck and behavior to make adjustments.
What room temperature should I aim for to reduce overheating risk?
Aim for a comfortable nursery temperature around 68–72°F (20–22°C). This range helps balance the risk of overheating and being too cold. If your home runs warm, use breathable clothing, arms-only swaddles, and consider a fan or adjusted thermostat to maintain airflow and consistent temperature.
