It was only a month or so ago that the world got a glimpse of baby Archie with the Duke and Duchess of Sussex in Africa as he clung to his mother.

Fast-forward a few weeks and the six-month-old has learned to crawl.

During an unannounced visit with military families, Meghan Markle revealed to another mother that her son is on the move.

“My daughter Aeris is the same age as Archie and we talked about weaning and the children beginning to crawl—she’s just a normal mom and it was like talking to a friend,” said Amy Thompson.

And along with crawling, Archie also has his first two teeth.

In a video posted on the SussexRoyal Instagram account, Meghan is kneeling down while chatting with a young girl.

“Look at all your little teeth!” the duchess said. “Archie just got two teeth, two tiny ones right there” she added while pointing to her bottom centre teeth.

Yesterday, The Duke and Duchess surprised their neighbours in Windsor at a coffee morning for military families in a community centre located in the heart of the Army housing estate. Every year during the month of November we pause to remember and honour all those who have served their country here in the UK, across the Commonwealth and around the world. Their Royal Highnesses also wanted to show support for the families of service personnel who are currently deployed overseas. As we lead up to Remembrance Sunday, The Duke and Duchess of Sussex will join Her Majesty The Queen and other Members of the Royal Family at various commemoration events, including the Festival of Remembrance at the Royal Albert Hall and the Cenotaph. During the visit yesterday, Their Royal Highnesses met with young families who shared their experiences as parents and as couples who are often apart from their loved ones for months at a time. A reminder that a life of service does not simply describe the person wearing the uniform, but the entire family. #Remembrance #Lestweforget

Both will accompany Queen Elizabeth II and other members of the Royal Family at the annual Royal British Legion Festival of Remembrance on Saturday and the annual Remembrance Day Service at the Cenotaph on Sunday.

Shortly after, the family of three will head to the United States where they will spend Archie’s first Thanksgiving with Meghan’s mother Doria Ragland.
