The Duchess of Sussex has revealed that baby Archie has started trying to walk.
She let slip he had reached the adorable milestone during a visit to Robert Clack Upper School in Dagenham, east London on Friday, in one of her last engagements as a senior royal.
Meghan spoke at the school ahead of International Women's Day.
While talking to Geraldine Dear, one of the 'Dagenham Girls' who went on strike at the nearby Ford Motor Plant in 1984 to demand equal pay for women, she admitted that ten-month old Archie has been attempting to get up on his feet.
Recounting their conversation, 66-year-old Ms Dear said: "I just had to ask her about the baby."
"She said to me, 'he's exactly ten months today and he's started trying to walk."
The Duchess paid tribute to Ms Dear for her historic role in campaigning for equal pay when the pair met.
She said: "Well done on making such an important change for this country. I'm sure it's not an easy thing to do but it's the right thing to do."
In a speech, Meghan also told the school's boys to "value, appreciate and protect" women.
She urged them to "continue to value and appreciate the women in your lives and also set the example for some men who are not seeing it that same way."
During the same visit, the Duchess told a student that having her son had "changed her life".
Olivia Collins, a Year 13 student, said: "She was talking about how having Archie has changed her life and how important motherhood is."
Baby Archie has not been seen in public since Meghan and Harry shared a picture of him on a beach with his father on Instagram on New Year's Eve.
His parents are currently carrying out their last official engagements before they step back as senior royals at the end of the month.
Meghan is on her first visit back to the UK since the couple announced they would be giving up royal duties in January.
The Duke and Duchess's son, however, remains in Canada, where he is believed to be staying with his nanny and Jessica Mulroney, Meghan's best friend.
It was reported that the Queen was 'very sad' that Archie, who has spent the last three months in North America, had not accompanied his parents on their visit.
