Footage from the incident shows the young prince stumbling up the hill. After he reached the top to sit beside his sister Princess Charlotte, Savannah shoved him, sending him back down the knoll.
While Prince William was busy playing in the polo match, George's mother Kate Middleton was standing nearby. A photo from the event showed the Duchess of Cambridge comforting her 4-year-old son. Although, it's unclear if the photo was taken before or after the incident.
Luckily, the little prince seemed to be OK and climbed up the hill again.
