STOCKHOLM (AP) — Crown Princess Victoria's newly born son and second child has been christened Oscar Carl Olof.

The baby prince, born March 2, grunted Friday when water was poured on his head during a ceremony at the Royal Palace's chapel in Stockholm, which was packed with Scandinavian royals and guests.

Oscar later appeared on his mother's arm before a crowd outside the palace where fans snapped photos and a 21-gun salute rang out.

He is third in line to the throne after his mother and 4-year-old sister, Princess Estelle.

In 1980, Sweden changed its constitution to allow the eldest heir to inherit the throne, regardless of gender. Before that, female heirs were excluded.

Victoria's father, Carl XVI Gustaf, has been king since 1973. The Swedish royal family's duties are ceremonial.
