As temperatures dip and winter sets in, one of the biggest concerns for parents is ensuring their baby stays warm and safe while sleeping. While piling on blankets might seem like a good idea, loose bedding is not safe for infants. Instead, sleep experts recommend wearable blankets, also known as sleep bags, as the safer and more effective solution for cold nights.In this article, we’ll explain why sleep bags are better than blankets in the winter, how to choose the right TOG rating, and why SwaddleAn’s 2.5 TOG bamboo sleep bags are a winter essential for your baby’s sleep routine.
Why Blankets Aren’t Safe for Babies
Babies under 12 months should never sleep with loose blankets or pillows. According to the American Academy of Pediatrics (AAP), these items can increase the risk of SIDS (Sudden Infant Death Syndrome) by covering your baby's face and affecting their ability to breathe.That’s why sleep bags are the go-to choice for winter. A sleep bag wraps around your baby like a wearable blanket, providing consistent warmth throughout the night without shifting, bunching, or falling off.
The Benefits of Winter Sleep Bags
Sleep bags aren’t just safer—they’re more convenient and comfortable for both babies and parents. Here are some of the top reasons families switch to sleep bags during the colder months:
- No Kicked-Off Covers: Babies naturally wiggle in their sleep. A sleep bag stays in place all night long.
- Even Warmth: Unlike blankets, sleep bags provide even insulation from chest to toe.
- Better Sleep Cues: Putting on a sleep bag each night signals to your baby that it's time for sleep.
- Reduces Overheating Risks: Breathable materials help regulate body temperature naturally.
- Aligned with AAP Guidelines: Designed with safety in mind—no hoods, no sleeves, arms-free.
Understanding TOG: What’s Best for Cold Nights?
TOG stands for Thermal Overall Grade, and it indicates how warm a fabric is. The higher the TOG, the warmer the sleep bag.For cold winter months or room temperatures between 61–68°F (16–20°C), pediatricians and sleep consultants recommend a 2.5 TOG sleep bag. It provides enough insulation to keep your baby warm while preventing overheating.
| Room Temperature | Recommended TOG |
| 61–68°F (16–20°C) | 2.5 TOG |
