Archie is already working on his royal smile. Meghan shared a new milestone for her son during asurprise outing with military familiesearlier this month. As she met a group of young children at the Broom Farm Community Centre in Windsor, Meghan told one little girl, “Look at all your little teeth! Archie’s just got two teeth.”

She pointed to her bottom lip as she added, ”Two tiny ones right there.”

It’s unclear when royal fans will see the Sussex family next. It was previously revealed that Meghan and Harry willtake about six weeks offtowards the end of the year to spend some valuable “family time” together amid their concerns that theintense scrutinythey’ve faced has been tough on the couple.

“The duke and duchess have a full schedule of engagements and commitments until mid-November, after which they will be taking some much-needed family time,” a royal source confirmed to PEOPLE.

And it was shared earlier this week that Meghan and Harry are skipping the annual holiday festivities at Sandringham — including their public walk to church on Christmas morning — withQueen Elizabethand the rest of the royal family.
