Something about snuggling under the covers makes bedtime cozy, but babies can't have loose blankets in their sleep space. Sleep sacks are the perfect alternative. They’re safe for babies and toddlers while also providing that extra comfort at bedtime. Plus, they stay in place so your toddler won't throw all the covers off and end up shivering by morning.

What Are Tog Ratings on Sleep Sacks?
TOG is an acronym that stands for "Thermal Overall Grade." A TOG rating indicates how warm a blanket or article of clothing is. The higher the TOG rating, the better it will keep you warm in cold temperatures. Lower TOG ratings are items best for warmer weather.
Each company may have its own TOG rating. Typically, a TOG rating comes alongside temperature recommendations for the ideal air temperature when you use or wear the clothing or blanket.
How to Choose the Best Sleep Sack
Choose a sleep sack based on the temperature in your house, season, and your preferences. You can adjust layers of clothing underneath the sleep sack to adjust for changing temperatures.
