Made of 100% cotton, the NEW Ergobaby Easy Snug Infant Insert is intuitive and easy to use, and provides your baby with a gentle transition from womb to world. Required for carrying your little one from birth until head control has been established (3.2 to 5.5kgs), the Infant Insert comprises two key components – the cushioned outer shell and a removable pillow. Both of these components are used from birth to provide an ideal fetal position and, as baby grows, can be separated to accommodate baby’s natural straddle. The new and improved design is compatible with any Ergobaby Original or 360 Carrier.
