WATCH: Meghan kneels down to accept a rose and share stories with a little girl: 'Archie just got two teeth!'

Cape Town – The Duke and Duchess of Sussex gave their neighbours in Windsor a royal surprise this week when they had coffee at a community housing centre located in the hear of the Army housing estate.

According to the Sussex Royal Instagram account, every year in November, Their Royal Highnesses remember and honour those who served their country in the military. For Harry it's a particularly important time, having served as an army officer himself for ten years, reports Independent.

According to Army & You, who covered the event exclusively, His Royal Highness said, "It's unbelievably hard. I have so much respect and admiration for anyone who has to deal with that." Having just become a dad himself, and with Archie hitting the six-month-mark this week, he continued acknowledging how much harder it must be for parents. He said, "I can't imagine what it's like to miss so much as they change so quickly."

Their Royal Highnesses visited families of service personnel who are currently deployed overseas and spoke about what it's like to be away from the people they love for long, all the while sharing experiences of what it's like being a parent – Meghan even divulged an update or two about Archie.

Army & You reports, according to Amy Thompson whose husband, Brad, is attached to the Welsh Guards, Meghan spoke to the mom about Archie and revealed the littlest royal is weaning and already crawling. "She's just a normal mum," Amy said. "And it was like talking to a friend."

Before leaving, Meghan also accepted a rose from a little girl and shared another sweet update about Archie. She kneeled and said, "Look at all your little teeth. Archie just got two teeth.

"Tiny ones, right there," she said, pointing to her bottom set.
