More Wikipedia - "Princess of Wales - On 9 November 1901, nine days after arriving back in Britain and on the King's sixtieth birthday, George was created Prince of Wales. The family moved their London residence from St James's Palace to Marlborough House. As Princess of Wales, May accompanied her husband on trips to Austria-Hungary and Württemberg in 1904. The following year, she gave birth to her last child, John. It was a difficult labour, and although May recovered quickly, her newborn son suffered respiratory problems.* From October 1905 the Prince and Princess of Wales undertook another eight month tour, this time of India, and the children were once again left in the care of their grandparents. They passed through Egypt both ways and on the way back stopped in Greece. The tour was almost immediately followed by a trip to Spain for the wedding of King Alfonso XIII to Victoria Eugenie of Battenberg, at which the bride and groom narrowly avoided assassination. Only a week after returning to Britain, May and George went to Norway for the coronation of King Haakon VII and Queen Maud (George's sister). (Continued)
