One Instagram user wrote, “Sorry, I don’t agree with the photo’s choice. Where are Charlotte and George? Where is Kate’s father?”
A second wrote, “Apparently Kate doesn’t have a dad and William only has one child 🤣 Happy fathers day!”
And a third voiced the same concern: “Where’s Prince George and Princess Charlotte plus Catherine’s father?”
While two of his children were missing from the Father’s Day tribute, the entire family were present at the Trooping the Colour earlier this month.
The event - which is held in honour of Queen Elizabeth’s birthday - marked the first time little Louis appeared on the Buckingham Palace balcony.
