The couple, who left their frontline royal duties for good last year, are reportedly planning to have their youngest daughter baptized in the same location as her brother.
If this continues, it would be the first time Meghan has returned to the UK since 2019.
A royal source told the Daily Mail: ‘Harry has told several people that they want Lili baptized in Windsor, just like her brother.
“They are happy to wait until circumstances permit. “
The eldest child Archie was baptized in the private chapel at Windsor Castle in July 2019.
Last month, the couple announced the birth of their second child, named after their great-grandmother, the Queen.
The Duke of Edinburgh, who died in April, used the name Lilibet as a pet for the monarch, although it was originally given to him by his grandfather, King George V, due to the way she pronounced her own name.
Writing to his mother-in-law, the Queen Mother, on their honeymoon, the Duke said, “Lilibet is the only ‘thing’ in the world that is absolutely real to me. “
Harry and Meghan announced the birth of their daughter last month, claiming that she bears the Queen’s name.
A statement from the couple’s press secretary said: “It is with great joy that Prince Harry and Meghan, The Duke and Duchess of Sussex, welcome their daughter, Lilibet ‘Lili’ Diana Mountbatten-Windsor, in the world.
“Lili was born Friday, June 4 at 11:40 am under the trusted care of doctors and staff at Santa Barbara Cottage Hospital in Santa Barbara, California.
“She weighed 7 pounds 11 ounces. Both mother and child are healthy and doing well at home.
“Lili is named after her great-grandmother, Her Majesty the Queen, whose family nickname is Lilibet. “
Harry has returned to the UK twice this year – once for the Duke of Edinburgh’s funeral and once for the unveiling of a statue of his mother, Princess Diana, earlier this month.
Her relationship with her family has been in the spotlight since an explosive interview with Oprah Winfrey, in which the couple alleged that an anonymous royal made derogatory remarks about Archie’s skin color.
He also claimed that his father and brother were “trapped” in their roles and that Prince Charles had stopped responding to his calls.
