Kate Middleton was accused of being fed up with her 4-year-old daughter Princess Charlotte.

On the online forum site Quora, one royal fan uploaded a throwback photo of the Duchess of Cambridge seemingly asking Princess Charlotte to calm since the latter was throwing a tantrum.

Margaret Challen, the studied at the University of British Columbia, said that Prince William’s wife looks fed up in the snap. She also said that her sister sent her the photo of Middleton and Princess Charlotte and said that even royal kids throw tantrums.

“P.S. Sue McCune Martin has also answered this question and has several greater pictures. The duchess’s facial expression in all these pictures seems to be, 'I cannot totally lose my shit in front of all these cameras, but this kid is working my very last nerve!'" Challen said.

Martin, who observes, reads, and studies the British Royal Family, said that it is quite obvious that the Duchess of Cambridge is the one that plays the role of the enforcer in the Cambridge household.

In one of her snaps with her children, it seems that Middleton is once again reprimanding her kids. But this time around, she seems upset with Prince George. Another photo was taken at Pippa Middleton’s wedding, and it seems that Middleton is giving Prince George a lecture.

Cheryl Clair, a former housewife, also echoed the other royal fans’ statements.

“Yes, on more than one occasion. Famously she got on to Charlotte on the tarmac in Germany and she was seen reprehending George at one of the weddings. I think it was her sister Pippa’s wedding. She’s a hands-on mom,” she said.

But it is important to note that Middleton might not have necessarily been fed up with her kids. The Duchess of Cambridge might simply be trying to calm them down since they are in public. And as a mom of three, the royal is definitely aware that tantrums among young children are normal.
