Prince William celebrated Father’s Day with a special post that stirred some of the netizens.

On Sunday, the Duke of Cambridge took to Instagram to share two adorable photos. In one snap, he can be seen having a great time with 13-month-old Prince Louis. The father and son are looking at each other with Prince William trying to entertain his youngest child.

The second photo features Prince Charles and Prince William walking alongside each other with a helicopter in the background. The picture was taken when the Duke of Cambridge showed the Prince of Wales around the RAF Rescue helicopter at RAF Valley in 2012.

However, a number of netizens reacted negatively to the photos. Many were wondering why Prince William chose those pictures that didn’t include his two other children Prince George and Princess Charlotte. In addition, it wasn’t enough for them that he paid tribute to his father, Prince Charles, and not to his father-in-law, Michael Middleton.

“Sorry, I don’t agree with the photo’s choice. Where are Charlotte and George? Where is Kate’s father?” one user commented.

“Apparently Kate doesn’t have a dad and William only has one child. Happy fathers day!” a different user added.

Prince William and Middleton were last seen with their three children at Trooping the Colour. Prince Louis made his debut at the Buckingham Palace balcony on the said event and stole the show with his adorable wave.

In one video, Prince William is seen carrying Prince Louis who is sucking his thumb. Middleton tried to stop him from doing his bad habit in public, but Prince Louis kept on putting his hand in his mouth.

Prince George and Princess Charlotte’s attendance also pleased the royal watchers. Prince William and Middleton’s only daughter sported two new hairstyles at the event and she was in high spirits. Princess Charlotte was seen waving the whole time with one netizen comparing her wave to a car’s wiper.

In related news, according to body language expert Judi James, Middleton changed after welcoming Prince Louis. She is more relaxed. The Duchess of Cambridge’s smile also suggests a more “genuine” delight.
