BabyBjorn Baby Carrier I purchased this new and used it until my child was about 4 months old. This type can be used from before the baby can hold their head up. It shows some signs of use, but it's still in good condition. In the summer, this BabyBjorn baby carrier is easier to use than the Aprica one because of its mesh fabric! It can be washed in a laundry net. A storage bag is also included.
