A child carrier for carrying two children of different sizes has a first and second child carrier portions including first and second carrier pouches, respectively, each pouch attached at its bottom to a waist support, and shoulder straps. The first and second child carrier portions are configured to be secured between the shoulder straps and directly opposite one another. At least one of the child carrier pouches is configured to extend behind the shoulder straps, such that a heavy weight in the opposite child carrier pouch that presses the shoulder straps tightly against a wearer does not compress a child therein against the wearer. Each of the child carrier pouches is curved towards a wearer to prevent a child inserted therein from facing away from the wearer and is configured to hold a child in a seated straddle position.
