Talk about adjustable! 🤩 The Boba X regulates in width and height to fit from birth to toddlerhood and beyond - no infant insert needed! 🙌 Just one smooth slide and you can go from snuggling your newborn on your front to wearing your big babe on your back! ❤️ Keep them supported in an ergonomic position from knee to knee with added extensions that can bring the seat from as little as 20cm to as wide as 53cm - wider than most toddler sized carriers! 🌟 | Boba
