Quick answer
Dress your baby in a single-layer sleeper made of breathable fabric like TENCEL Lyocell, then check for a comfortable room temperature and avoid loose bedding or extra layers that could cause overheating.
Why fabric choice matters for sleep safety
Breathable fabrics help regulate your baby's temperature and reduce the risk of overheating during sleep. TENCEL Lyocell is a great option because it wicks moisture away from the skin and stays soft even after many washes. Avoid synthetic materials that trap heat or cause sweating.
When to add or remove a layer
A good rule of thumb is to dress your baby in one more layer than you feel comfortable wearing at the same room temperature. If the room is 68-72°F (20-22°C), a sleeper alone is usually enough. Check your baby's neck or back to see if they feel warm or sweaty—adjust layers accordingly.
How to dress your baby for sleep in a sleeper
- Choose the right sleeper fabric: Select a sleeper made from breathable, moisture-wicking material like TENCEL Lyocell. Avoid fleece or heavy knits that can cause overheating. Check that the sleeper fits snugly but not tightly—no extra fabric that could bunch up. A well-fitting, breathable sleeper is the foundation of safe sleep.
- Dress baby in one layer only: Put the sleeper on over a diaper. Do not add a onesie, swaddle, or blanket underneath. The sleeper itself is the sleep layer. If the room is cool, use a sleep sack over the sleeper instead of adding extra clothing. Over-layering is a common mistake—stick to one layer for the sleeper.
- Check room temperature and baby's comfort: Keep the nursery between 68-72°F (20-22°C). After dressing baby, feel their neck or back—if it's warm or sweaty, remove a layer. If it's cool, add a sleep sack. Never use loose blankets or bumpers. The neck check is your best tool for judging if baby is comfortable.
