BabyBjorn ONE I also used other baby carriers, so I didn't use this one very often. It was useful indoors for the newborn stage and for putting the baby to sleep, as well as for easily putting the baby down after they fell asleep. Would you like it as a spare or for indoor use? Please understand that this is a used item, that it has been inspected by an amateur, and that it has been stored by an amateur before purchasing. There is a possibility that it will be compressed to some extent for shipping. Thank you.
