Kate Middleton is said to have shared a lovely moment with palace staff after Prince Louis was born.
A palace insider explained: “The Princess of Wales is very popular with staff.
“I remember after Prince Louis was born, she popped into Clarence House, quietly knocked on the door of the staff quarters and introduced them all to the baby.
“They were really touched by that,” .
And it seems being naturally well-liked runs in the family because Prince Louis has fondly become known as ‘Boss Baby’ amongst royal fans in recent years.
It comes after the Prince and Princess of Wales’s youngest son has showcased his incredibly independent personality and bold facial expressions during several public appearances.

To his parents, however, Prince Louis’s nickname is believed to be ‘Lou Bug’.
Earlier this year, when the Wales family stepped out at a Scout’s event in Slough, Kate encouraged her son to “pop [the skewers of marshmallows] in the fire, Lou Bug”.
The future king and queen have also given Princess Charlotte and Prince George nicknames.
Charlotte is referred to as “Lottie” by Kate, whereas William calls her “Mignonette”, which means dainty or cute in French.

George, on the other hand, is rumoured to be called “PG” at school, which his parents have yet to confirm in public.
It comes after last night, when Prince Louis joined his siblings and parents for the Together at Christmas carol concert at Westminster Abbey.
He was seen blowing out Charlotte's candle, as well as marvelling at the Christmas decorations - including a giant Nutcracker - before marching out of the Abbey where he mimicked a transformer.
