The tiny royal stayed perfectly collected during the ceremony, not even shedding a tear as Archbishop Antje Jackelén poured water on his head.

Prince Alexander’s cousins, 4-year-old Princess Estelle and 2-year-old Princess Leon were also in attendance, along with Prince Oscar, 6 months, and Princess Estelle, 4.
