In the sweet family photos, a small Kate Middleton wears a lovely white christening gown while her parents and other family and friends smile happily at the event.
The 11-week-old will be christened at 4pm in the Chapel Royal at St James's Palace. She is thought to have a close bond with both William and Harry to this day, and was a guest at Prince Harry and Meghan's wedding.
On May 19, before she had even confirmed she was expecting, Pippa seemed to be glowing at Meghan Markle and Prince Harry's wedding in a mint green and patterned silk dress.
According to Royal tradition, water from the River Jordan should be used for the christening.
Pippa Middleton flaunted her growing baby bump in an elegant summer dress while braving the crowds at Wimbledon with her brother James.
The cream lace and white robe is a replica of the gown made for Queen Victoria's eldest daughter's christening in 1841.
Here are 13 times Kate Middleton and Princess Charlotte had the flawless mother-daughter style.
Newlyweds the Duke and Duchess of Sussex are likely to put in an appearance, as are Kate's pregnant sister Pippa Matthews, and her brother James Middleton. Louis, born on St George's Day, will be dressed in the same gown worn by Prince George, four, and Princess Charlotte, three, for their christenings.
It is fitting to see the lovely pictures of Kate Middleton's baptism as her third child's special day approaches. The only royal family member to get that distinction was Zara Tindall, the daughter of Princess Anne, who was named as one of George's seven godparents in 2013.
