The little royal, Prince Alexander made his first official public appearance in Stockholm for the National Day celebrations. Alexander was joined by his parents, Prince Carl Philip and Princess Sofia, as the family of three waved and spoke to the gathered crowd. Also in attendance were Alexander's cousin, Princess Estelle, and her parents, Prince Daniel and Princess Victoria. While Alexander stayed bundled up safely in his mother's arms, Estelle, who, along with the rest of her famous family, wore traditional Swedish clothing, rode in a carriage. While Prince Oscar sadly didn't appear to be a part of the big day, the world did get adorable glimpses of him when he was christened last month. Such a sweet family!
