The Duchess of Cambridge recently took part in a meet-up for parents of new students at the Hollywood Arms pub and restaurant in the Chelsea neighborhood of London, reports the Mail on Sunday. In September, Kate, Prince William and 6-year-old Prince George memorably accompanied 4-year-old Princess Charlotte to her first day of school at Thomas’s Battersea, a $23,000-a-year private school. So how was Kate able to sneak in the pub undetected? By using a secret entrance — that some say was installed so that her brother-in-law Prince Harry could imbibe at a local joint without causing a huge stir. When it comes to her own three children, including 1-year-old Prince Louis, Kate is “so hands-on and involved with everything,” a source previously told PEOPLE.

George and Charlotte kicked around a soccer ball with Kate cheering them on (when she wasn’t running after Louis, that is!). When stomachs started rumbling, they retreated to the car for a snack break. Kate and her kids munched on food packed in lunchboxes with the trunk popped open and the royal mom taking a seat on the grass. Can’t get enough of PEOPLE’s Royals coverage?
