The couple had residences at Kensington Palace and Highgrove House, near Tetbury. On 5 November 1981, Diana's pregnancy was announced. In January 1982—12 weeks into the pregnancy—Diana fell down a staircase at Sandringham, suffering some bruising, and the royal gynaecologist Sir George Pinker was summoned from London; the foetus was uninjured. Diana later confessed that she had intentionally thrown herself down the stairs because she was feeling "so inadequate". On 21 June 1982, Diana gave birth to the couple's first son, Prince William. She subsequently suffered from postpartum depression after her first pregnancy. Amidst some media criticism, she decided to take William—who was still a baby—on her first major tours of Australia and New Zealand, and the decision was popularly applauded. By her own admission, Diana had not initially intended to take William until Malcolm Fraser, the Australian prime minister, made the suggestion.
