The royal baby is here, officially making Doria Ragland a grandmother.
The Royal Family Twitter account said Meghan's mom was by her side at Frogmore Cottage when the baby arrived.
"The Duchess's mother, Doria Ragland, who is overjoyed by the arrival of her first grandchild, is with Their Royal Highnesses at Frogmore Cottage. Her Royal Highness and the baby are both doing well," the tweet said.
The baby was born at 5:26 a.m. local time, according to Buckingham Palace. He weighed 7 pounds, 3 ounces and is seventh in line to the British throne. Harry was at Meghan's side and both mom and baby are "doing well," the palace said in a statement.
As the new parents Prince Harry and his wife Meghan welcomed their child, many royal watchers have been looking at how the baby's two grandmothers -- Princess Diana and Doria Ragland -- will play a role in the child's life as they come of age.
If Meghan has any doubts about embracing her new role as a royal mom, she need look no further than the example set by her late mother-in-law, Diana.
"She's a massive missing part of their lives," ABC News' royal contributor Imogen Lloyd Webber said of Diana. "And she will be front and center."
When it came to raising her young princes, Diana set a gold standard, always doing her best to ensure they had a regular childhood.
In 1995, she spoke to the BBC about how she hoped to raise her sons, saying, "I want them to have an understanding of people's emotions, people's insecurities, people's distress, and people's hopes and dreams."
"And they have a knowledge -- they may never use it, but the seed is there, and I hope it will grow because knowledge is power," she added.
In 2016, Harry told ABC News' Robin Roberts that he's worked hard to keep that spirit alive.
"I hope she's looking down, you know, with ... tears in her eyes, being incredibly proud of what we've established," he said. "I hope that everything we do privately and officially ... that it makes her proud."
Meghan's own mom, Ragland, is staying in the couple's newly-renovated cottage in Windsor when the baby comes, and many expect her to be a very involved, doting grandmother.
"There's absolutely room for Granny Doria to come and visit," Lloyd Webber said.
"She was caught taking baby care classes before the announcement that Meghan was pregnant, so absolutely she will be there on site," she added. "No doubt a very hands-on grandmother."
Meghan grew up with an interest in the world around her thanks to her mom, who's a social worker and yoga instructor in California. And just like Diana, she has become deeply dedicated to humanitarian work.
While Diana is not around to help raise the newborn, royal watchers say her spirit and legacy will definitely be palpable as the baby grows up.
"I think both Diana and Doria, though they never met, shared an emotional intelligence which they've given to their children," Lloyd Webber said. "Diana was all about making the monarchy more approachable and accessible, and I think Meghan and Harry are the living, breathing embodiment of that."
