Prince William posts a Father's Day photo with Louis. But, oops, where are George and Charlotte?

Royals, they're just like us: They celebrate Father's Day with cute Instagram posts. But some are criticizing Prince William for being a little too selective with his photo choices this year.

In an Instagram post from @kensingtonroyal (the joint account for Prince William and Duchess Kate), the couple wished everyone a Happy Father's Day, just as Prince Harry did with his post showing a new photo of baby Archie.

But William's post raised eyebrows after fans pointed out the photos excluded a number of royals: The first image depicted only William and his youngest son, 1-year-old Prince Louis. The second showed William and his father, Prince Charles.

Fans wondered in the comments why the prince didn't pose with all three of his kids for the occasion – and why Duchess Kate and her dad weren't included.

"(Kensington Palace) made no effort at all in making this post," one user criticized. "Where are pictures of him with his other two children?"

"And what about Papa Middleton?" another questioned.

Another user quipped: "Seriously, does William not have a pic of him and all three of his children?"

Others argued the post shouldn't be taken "so seriously" – both photos shared were just nice snapshots from Will's life.

"This has to be one of my fav photos of William as a father... the look from Louis to his dad is priceless. Such a look of trust."

"I love this," one user wrote. "No self promotion, simple words that encompass and apply to all ... Two lovely pictures that show us what (the holiday) means to William."
