Diana, Princess of Wales will be keenly missed by the Duke of Sussex as he celebrates the birth of his first child with family and friends.
Harry was aged just 12 when his mother died following a Paris car crash in 1997 and he has faced major milestones in his life without her guidance and support.
But the duke has talked about feeling her presence and has strived to include some token from his mother during important moments.
Two diamonds from Diana’s personal collection were used in the engagement ring he designed for his wife and he has said he wanted the princess to be part of his and Meghan’s “crazy journey together”.
Harry said when his engagement was announced in November 2017: “It is days like today when I really miss having her around and miss being able to share the happy news.
“But, you know, with the ring and with everything else that’s going on, I’m sure she’s with us, you know, jumping up and down somewhere else.”
Meghan echoed his thoughts at the time saying: “She’s with us.”
The ring also featured a stone from one of the couple’s favourite places, Botswana, and when asked what his mother would have thought of his then fiancee, Harry replied: “Oh, they’d be thick as thieves, without question.”
The duchess has met Diana’s closest friend, Julia Samuel, while all of the princess’s siblings were at Harry and Meghan’s wedding – Earl Spencer, Lady Sarah McCorquodale and Lady Jane Fellowes, who gave a reading.
From passing out from Sandhurst and starting his military career to marrying Meghan and having his first child, the duke is likely to think she is still part of his life.
The duke and duchess’s engagement photo call was held in the Sunken Garden of Kensington Palace – the site of the memorial garden created in Diana’s memory to commemorate two decades since she was killed.
The Sunken Garden was one of the princess’s favourite parts of the palace grounds.
Harry and his brother, the Duke of Cambridge, have commissioned a statue to mark the 20th anniversary of Diana’s death, which will be erected in the grounds of her former home Kensington Palace.
Both princes are still living with the devastating emotional impact of their mother’s death.
The image of a young William and Harry walking behind the horse-drawn gun carriage transporting their mother’s coffin through the streets of London on the day of her funeral has become etched in the public’s memory.
But they have come through the trauma to forge ahead with their own lives.
On the day Meghan and Harry showed their baby boy to the world, there is no doubt the duke would have wished his mother was there. ends
