Paola Ciabattini holds up her 19-month-old son Daniele De Sanctis, dressed up as a pope, during Pope Francis' weekly general audience in St. Peter's Square at the Vatican, Wednesday, Feb. 26, 2014. Francis kissed the child as the new must-have Carnival costume made its debut at the pope's general audience Wednesday. Daniele, who was crying, was hoisted up to Francis as he drove by in his open-topped jeep. During Carnival in Italy, children often go to school and spend their weekends dressed up in pirate, princess   and now pope   costumes. Carnival, also known as mardi gras, marks the period before the church's solemn Lenten season begins. Ciabattini said she dressed her son as a pope in a demonstration of affection towards Pope Francis.
