Canadian Prime Minister Justin Trudeau shared adorable photos of his son Hadrien's visit to his office last Thursday (May 11).
They raced down hallways, Hadrien pretended to scare his father, and they faced the press together.
In one photo, the three-year-old looked serious as he tapped on a smartphone while sitting at his father's desk.
The adorable photos, posted on Facebook, elicited oohs and aahs on social media.
Some netizens said the photos reminded them of occasions when Mr Trudeau appeared with his father, Pierre, a former prime minister, years ago.
Given the all-consuming nature of a politician's work, Mr Trudeau is not the only one whose children have appeared in the limelight while at work.
1. Malia and Sasha Obama
Former US President Barack Obama's daughters, Sasha and Malia, have often appeared at official functions and accompanied their parents on trips.
On a trip to Cuba last year, Malia, 18, helped her father as a Spanish-English translator.
Sasha, 15, and her sister also accompanied mum Michelle on a trip to promote education in Africa in June last year.
2. Florence Rose Endellion Cameron
Former British Prime Minister David Cameron's daughter Florence Rose stole the show when he announced he was stepping down last July.
The six-year-old looked forlorn as Mr Cameron announced that they would be leaving No 10, Downing Street.
He shared that his children would sometimes kick the official red boxes that contained government documents - and work for their father.
"Florence you once climbed into one before a foreign trip and said 'take me with you'," he shared in a speech.
3. Arabella and Joseph Kushner
More recently, the Trump grandchildren made an appearance at a bilateral meeting between their grandfather, US President Donald Trump, and Chinese President Xi Jinping.
Arabella Kushner, the eldest child of first daughter Ivanka, sang a Mandarin song to Mr Xi and his wife Peng Liyuan.
