This is a great fun set! My kids love playing with this! They put the babies into the crib and high chair that came with their doll house. The babies are 2 inches long and are very cute. Their neck doesn't move but their arms move up and down and their legs move up and down but only a little. The barbies left arm stays bent to hold the babies and her right arm moves up and down, her legs move up and down, and her neck moves side to side.
