Designed for babies aged 6 to 36 months, Tommee Tippee newborn and baby sleepbags are made with soft cotton fabric that’s kind to your baby’s skin, soothing at nighttime and easy to wash (again and again). The bottom-to-top zip make blurry eyed nighttime nappy changes less of a challenge, and their specially designed wide bottom encourages a natural ‘frog-legged’ sleeping position and supports healthy hip development.
