"I can't imagine what it is to miss so much, since they change so fast", said the new father, for ITV News. Several adorable photos posted to the couple's Instagram account show Harry picking up a girl and the couple getting right down to eye level to chat with other children.
At the time, fans were confused, however the placement didn't necessarily mean the displacement of the two Duchesses was a slight against either of them.
Speaking of Archie, it seems that the little one has already reached some important milestones.
Prince Harry said he was "in awe" of the families who get on with their lives while their military partners are away for so long.
The visit marked one of the first of this week's engagements for Remembrance Day, a holiday that honors members of the Armed Forces, who have died in the line of duty.
But Harry and Meghan also wanted to show support for the families of service personnel who are now deployed overseas, it said.
Harry and Meghan paid their respects to servicemen and women who made the ultimate sacrifice in conflicts across the decades by planting tiny crosses in the Field of Remembrance.
"A reminder that a life of service does not simply describe the person wearing the uniform, but the entire family", a statement said.
The Duke and Duchess of Sussex honoured Britain's war dead on Thursday during a poignant ceremony at the Field of Remembrance outside Westminster Abbey at which Meghan was making her first appearance. The Field of Remembrance has been organised by the Poppy Factory and held in the grounds of Westminster Abbey since November 1928, when only two Remembrance tribute crosses were planted. It's open for 10 days a year, and this year Meghan and Prince Harry planted their own crosses in a attractive poppy-centric display.
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.
