Babies are delicate and require special attention, especially regarding their sleeping environment. Blankets can be dangerous for infants, as they can cause suffocation or increase the risk of sudden infant death syndrome (SIDS). However, sleeping with a blanket is safe once babies reach a certain age. But which things should parents remember in allowing babies to sleep in blankets? Here are some ideas.

1. Later Than 18 Months

It is recommended that babies do not sleep with blankets until they are at least 18 months old. Before that age, babies cannot move the blanket away from their face if it becomes a suffocation hazard. Instead, use lightweight sleepwear or a sleep sack to stay warm at night.

Meanwhile, sleep sacks are designed to provide a cosy, secure sleeping environment without the risk of suffocation or overheating. They come in a variety of sizes and materials. When choosing a sleep sack, look for one designed to fit your baby snugly but not tightly.

2. Three-Piece Outfits

Consider dressing them in a three-piece outfit to keep your baby warm and cosy at night. It consists of a onesie, footed pyjamas, and a wearable blanket. It will provide enough warmth for your baby without needing a loose blanket.

Ensure the wearable blanket fits your baby correctly and is not too loose or tight. Wearable blankets are a safer alternative to traditional ones as they are designed to fit snugly around your baby's body without the risk of getting tangled or trapped under the cover.

3. Room Temperature

The temperature of your baby's room is also essential for allowing them to sleep in blankets. The room temperature is recommended to be between 16-20°C (60-68°F) for optimal sleep conditions.

If the room is too warm, your baby may overheat; if it is too cold, it may become too cold, even with a blanket. Use a room thermometer to ensure your baby's room is at the right temperature for sleeping.

4. Nape of the Neck

When allowing babies to sleep in blankets, it is essential to ensure the veil is not too loose or tight. A loose blanket can quickly become a suffocation hazard, while a tight blanket can restrict breathing. The best way to ensure the veil is the right fit is to place it at the nape of the baby's neck. It will keep it in place while allowing your baby to breathe freely.

5. Overall Safety

Finally, it is essential to remember that allowing babies to sleep in blankets comes with risks. Ensure the blanket is lightweight and breathable materials such as cotton to minimise these risks. Always consider their safety first. If it intertwines with comfort, find safer ways.

Avoid using blankets with fringes, tassels, or other decorative elements that can become a choking hazard. Additionally, always place your baby on their back to sleep, and never allow them to sleep on their stomach or side.


Blankets can be a great way to keep babies warm and cosy at night, but it is essential to remember that they can also be dangerous. Wait until they are 18 months old to ensure your baby is safe while sleeping with a blanket, dress them in a three-piece outfit, monitor the room temperature, ensure that the blanket is the right fit, and always prioritise overall safety. By following these guidelines, you can provide your baby with a warm and comfortable sleeping environment while minimising the risks associated with blankets.
