TOG (Thermal Overall Grade) is the warmth rating used for baby sleepwear. It measures how well a fabric traps warm air to keep your baby at a comfortable temperature. The higher the TOG, the warmer the sleepwear, making it easier to choose the right SleepSack based on your room temperature.

What to choose: Swaddle vs. SleepSack
Both a sleepsack and a swaddle are used to help babies feel secure and comfortable while sleeping, but they serve different purposes and have distinct designs:
Swaddle: A swaddle is a type of cloth wrap used to tightly swaddle a newborn or young infant. It involves snugly wrapping the baby's arms and torso to mimic the feeling of being in the womb. Swaddling is believed to help prevent the startle reflex in infants, promoting better sleep by making them feel secure and comforted. It can also help regulate body temperature and reduce the risk of sudden infant death syndrome (SIDS) by preventing loose blankets from covering the baby's face. Swaddles are typically used in the early months of a baby's life, usually up to around three to four months old, depending on the baby's development and preferences.
Sleepsack (or Sleep Sack): A sleepsack, on the other hand, is a wearable blanket or sleeping bag designed for infants and young children. It comes in various sizes to accommodate different age groups. The sleepsack allows the baby to have their arms free and is not meant for swaddling. It is worn over the baby's sleepwear and provides warmth and comfort while ensuring there are no loose blankets that could pose suffocation risks. Sleepsacks are often used beyond the swaddling stage and are suitable for babies who can roll over and have more control of their movements.
How to transition to Wearable Blanket
When your baby shows signs of breaking free from the SleepSack Swaddle or rolling over, it’s time to discontinue swaddling. To make the transition easier, we recommend gradually transitioning your little one to the SleepSack Wearable Blanket. You can do this by swaddling your baby for a few nights with one arm out, then two arms out of the swaddle. Your baby will still have the secure feeling of the swaddle while gradually adjusting to having his arms free.

What should my baby wear underneath?
It is essential to dress your baby appropriately underneath the sleepsack or swaddle, depending on the room temperature. Use lightweight, breathable clothing, such as a onesie or a light cotton sleeper, in warm weather. In colder temperatures, opt for a warmer sleeper or footed pajamas.
