Sleep sacks are usually introduced around three months, but our sleep bags incorporate swaddles into some designs so you can use them from birth. Once your baby becomes a toddler, they can graduate to a loose blanket. Benefits of a Sleep Bag Safety and comfort are our biggest priority when it comes to bedtime. Here are some perks of using a sleep bag: Your baby gets better sleep because of the security they feel in an enclosed blanket (which means more sleep for parents too!) It keeps material from covering your baby’s face, unlike loose sheets and blankets that don’t stay put through the night It gives a correct and consistent body temperature, so the baby doesn’t overheat. To Swaddle or Not to Swaddle Some babies don’t like to be swaddled, and that’s okay, you can use a newborn sleep bag right away for a baby that doesn’t like being constrained. Swaddling should make your baby feel like they’re snug as a bug and mimic the feeling of being in the womb. You’ve seen this burrito-style wrap; it’s meant to restrict arm and leg movement in baby’s first few months and helps minimize wake-ups from their natural startle reflex while keeping their face safe from scratching. Switch to a sleep bag before they’re rolling over on their own—you don’t want them to get stuck facedown. We give you the best of both worlds. If you’re not sure whether your baby will respond to swaddling or you want an option that gives a smooth transition from swaddling to a sleep bag, we have designs that have removable swaddle wings. It’s a terrific option for parents that second-guess how to swaddle properly too, because our design is easy to use. Let’s Talk TOG All of our sleep bags have a Thermal Overall Grade (TOG) rating. This number indicates what kind of temperature the sleep bag is intended for. We have five different TOG ratings. A lower TOG, such as 0.25 TOG, 0.6 TOG, and 1.0 TOG, is made with lightweight fabric and meant for spring or summer. A heavier TOG, such as 2.5 TOG or 3.5 TOG are thicker and constructed for cooler months in fall and winter. FAQs About Our Sleep Bags Why should my baby use a sleep sack? Safety and comfort!
