Baby showers have only recently become popular in England, a royal expert tells ABC News, and "a lavish baby shower would be seen as highly inappropriate" on the part of the royal family. Any baby gifts given to the royal couple would likely be "respectfully returned," the source adds. In keeping with British tradition, the couple would accept gifts from family members and close friends after the baby is born.
Instead of a baby registry, William and Kate may ask for donations to some of their favorite charities — as they did when they got married, ABC News reports.
If Pippa does decide to throw a party for her sister, it would likely just be for friends. "The queen is not going show up at any party organized by Pippa," the royal expert tells ABC.
