This is a baby carrier for children who can hold their heads and sit up. It folds up small, so it doesn't take up much space when carrying it around. It's useful for when you usually walk but want to carry your child upright when they get tired. It covers from the back to below the knees and is used by supporting the back with one hand while carrying the child. It's perfect as a secondary baby carrier. The seller had it for disaster preparedness. Thank you.
