This carrier was a lifesaver for back carrying! For second children, back carrying is definitely easier than a baby carrier. It's great for taking care of the older child. I think I used it for about 8 months. The part that touches the baby's face is a little yellowed. I didn't mind it, but it's the part that would be covered by a separately sold cover. The abdominal holder part was good for increasing the baby's safety. Instruction manual included. It's a mesh material, so it's breathable, and it has cushioned shoulder straps for a comfortable baby carrier.
