Meghan, who sported a baggy khaki green over-sized midi dress, was pictured kissing Archie on the head as she made her way across the grounds.
Meghan and Harry had celebrated their son’s arrival with the Royal Family during his christening the previous weekend.
Princess Catherine, 43, was seen arriving at the match carrying Louis, who was later seen running around with his brother and sister.
Louis, now aged seven, was also seen sporting his mum’s sunglasses and cheekily walking over to Meghan and Archie with his tongue out.
Meghan and Harry announced that they were stepping down as senior working royals in early 2020, with the pair leaving the UK shortly after.
Having previously lived at Frogmore Cottage in Windsor, the family – including four-year-old Princess Lilibet – now live in California.
With the distance between the UK and the US, and the ongoing royal feud, it remains unknown when Archie and Lilibet last spent time with George, Charlotte and Louis.
