- Louis was born at St Mary’s, Paddington on April 23 – St George’s Day – 2018
These have been tough times for the Wales family, with Catherine still undergoing cancer treatment and the Monarchy stretched thin.
But there will be an outbreak of much-needed celebration today when their youngest child, Prince Louis.
Louis, brother to George, ten, and Charlotte, eight, turns six today.
Not that Charlotte will be eight for very much longer; there will be more cake and candles in just over one week’s time when, on May 2, she has her ninth birthday.
In just a few short years, Louis has already delighted the public, lifting our spirits with his cheeky attitude and energetic, wholehearted reactions, while the rest of his family observe the decorum of the moment.
Here, then, are some of the magic moments have made us smile – and a reminder of why this particular birthday boy is such a favourite.
