The Truth About Prince William And Prince Harry's Nanny

Tiggy Legge-Bourke became William and Harry's nanny in 1993, according to Tatler; Charles and Diana separated in 1992 (via History). Charles' decision to hire Legge-Bourke irritated Diana. She reportedly lamented, "Why does Charles need a substitute mother when [William and Harry] are with him?" (via Christopher Andersen's Game of Crowns: Elizabeth, Camilla, Kate, and the Throne, page 134).

Through Legge-Bourke's time as William and Harry's nanny, Diana became convinced she was the real woman Charles was having an affair with — not Camilla Parker-Bowles (via Game of Crowns, page 135). While this idea stayed with Diana, there was another reason she was no fan of Legge-Bourke: her relationship with William and Harry. According to Andersen, Legge-Bourke got on swimmingly with William and Harry, acting as a "surrogate mom." She often took them on trips to amusement parks, movie theaters, zoos, and fairs (Game of Crowns, page 134). The final straw, though, was when Legge-Bourke referred to William and Harry as her "babies" to the press (Game of Crowns, page 138). From that point on, Diana was determined to separate Legge-Bourke from her children.

In his biography of William and Kate (page 55), Anderson reveals Charles and Diana became amicable following their divorce, leaving him inclined to take her side when Legge-Bourke snubbed Diana's family during preparations for William's confirmation in March of 1997. When Diana complained to Charles of the slight, just one month later, Legge-Bourke was no longer the princes' nanny.
