As the days get longer and the temperatures rise, many parents start asking the same question: Does my baby still need a sleep sack during the summer? The answer is yes, but not just any sleep sack. Choosing the best baby sleep sack for summer can make all the difference in helping your little one sleep safely and comfortably through those warm nights.
Why Use a Sleep Sack in Summer?
Even in hot weather, a sleep sack (also called a wearable blanket or sleep bag) serves an important purpose. Babies, especially newborns, are still adjusting to the world outside the womb and can struggle to regulate their body temperature. A newborn wearable blanket keeps them cozy without the risks associated with loose blankets.
Unlike traditional blankets, sleep sacks stay securely in place and reduce the risk of suffocation or entanglement. They also help reinforce a consistent sleep routine by signaling that it’s time to wind down.
What Makes a Sleep Sack Summer-Friendly?
Not all baby sleep sacks are designed for summer. The best baby sleep sack for summer should be:
- Breathable: Look for lightweight materials such as 100% cotton, bamboo, or a cotton/poly blend.
- Sleeveless: Helps promote airflow and reduces overheating.
- Low TOG rating: TOG stands for Thermal Overall Grade, and it indicates how warm the fabric is. For summer, aim for a TOG between 0.2 and 0.5.
- Zippered with safety features: A quality sleep sack will include a zipper guard to protect the baby’s skin and make late-night diaper changes easier.
