A safer alternative to loose blankets in the crib, our Sleeping Bag keeps little ones warm and comfy all-year round, while a convenient two-way zipper gives parents easy access for diaper changes. With plenty of room for little legs to wiggle, kick, and stretch, it's the next step for post-swaddle, active babies. The custom-designed pattern on all of our Breathing Wear works with the Pro Camera's patented computer vision technology to safely detect your baby's breathing motion in almost any sleep position-without any sensors, electronics, or radars!-and sends real-time alerts should your little one need you.
