This baby carrier can be used from newborns. A dedicated drool cover is also included. I mainly used a stroller, so I've used this carrier less than 20 times. There are no noticeable stains, but since it has been used a few times, there is some looseness in the straps and scratches on the buckles. Purchased in September 2024. Baby Carrier On Main unit: Retail price 32,450 yen Drool cover: Retail price 2,200 yen Includes the main unit, drool cover, carrying bag, and instruction manual. The box is not included.
