This is a newborn insert specifically for the Ergobaby Original Baby Carrier. A baby waist belt is also included. Purchased 10 years ago and used only during the newborn period for four children. As shown in photo 4, there are some stains that cannot be removed. Perhaps this would be suitable for those who have an older Ergo and have had another baby? This infant insert is made of organic cotton and provides optimal support for your baby. - Brand: ergobaby - Material: Organic Cotton - Product Name: Infant Insert - Design: New Design - Features: Comfortable support for babies Thank you for looking.
