Which TOG Sleep Bag Should You Choose for Summer Nights?
This time of year, when the weather starts to warm up, we start putting away all the warm weather baby clothes & pulling out spring layers. This also has an impact on dressing baby for sleep - which is where TOG comes in. We've discussed TOG before, but as a refresher, it stands for Thermal Overall Grade, and is a measurement of a blanket’s thermal effectiveness – aka how well it keeps your baby warm. The higher the TOG number, the warmer the sleeping sack.

Babies aren’t good at regulating their body temperature, and overheating is a risk factor for SIDS. Choosing the right sleep sack will ensure they stay comfortable and safe while they sleep. A good rule of thumb is to never to dress a baby in more than one additional layer than an adult would find comfortable.

The most common TOG ratings you’ll see when looking for sleep sacks are 0.5, 1.0, and 2.5. So, what TOG sleep bag should you use for summer nights? For summer months and warmer weather, you’ll want to pick a sleep sack with a rating of 1.0 or lower. But keep in mind the temperatures below are based on your baby’s nursery, not the weather outdoors! So in some cases, if you keep the AC going all summer long, you may not want to change over your sleep sack out for a different TOG. 

Gunamuna has three different weights, since we know when it comes to safe sleep, options are always appreciated!
