The Love To Dream Swaddle Blanket is designed for babies aged 2-12 months. Made from comfortable cotton fabric, this transitional baby sleeping bag features patented zip-off wings to help gently transition your baby from being swaddled to arms-free sleeping. The 1.0 TOG rating makes it suitable for any season, providing a cozy and quiet sleep environment. The swaddle blanket is easy to use, allowing you to start by zipping off one wing and gradually transitioning your baby to a wearable blanket. It is machine washable and certified by the International Hip Dysplasia Institute.
