The Duke and Duchess of Cambridge have been busy making appearances in Stockholm [4] for their royal tour of Sweden and Norway [5], but there is one sweet moment you might have missed. After visiting the city with Crown Princess Victoria and Prince Daniel, the two sat down for tea with the Swedish royal couple's adorable children [6] Princess Estelle and Prince Oscar, at Haga Palace — and it's too cute for words. Not only does Estelle look adorable as she interacts with the British royals, but her brother looks like a little grown up in his business formal attire. Can we please get a play date between them and Prince George and Princess Charlotte [7]?
