Crown Princess Victoria and her two children — Princess Estelle, 8, and Prince Oscar, 4 — took a firsthand approach to learning about bees and their vital impact on the planet on Wednesday. They suited up in beekeeping suits — including adorable miniature versions for Estelle and Oscar! — to check out the beehives at Haga, which were a gift to the royal family from the Swedish Beekeepers Confederation 10 years ago. Princess Estelle, who is third in line to the Swedish throne behind her grandfather King Carl XVI Gustaf and mother, bravely held a honey super as her captivated little brother looked on. The royal siblings also leaned down with their faces close to the hive, perhaps to catch a whiff of the fresh honey.
