An abdominal torso element for a doll incorporates a receiving cavity with a first rotational element mounted in the torso element having an enlarged abdominal surface representing a pregnant abdomen and incorporating an associated fetal cavity. The first rotational element is positionable in a first closed position with the enlarged abdominal surface exterior to the torso element simulating pregnancy and a second open position with the enlarged abdominal surface received in the receiving cavity. A second rotational element is nested within the first rotational element and has an outer surface representing a non-pregnant abdomen. The second rotational element is positionable in a first open position and a second closed position with the non-pregnant abdominal surface exposed simulating a non-pregnant condition. A fetus/baby model is removably received within the fetal cavity and can be viewed and removed/inserted with the first and second rotational elements in the open position.
