Prince Louis will celebrate his 1st birthday on April 23rd which also happens to be St George's Day.
The young prince has only been seen a few times publicly- outside the Lindo Wing hours after birth, and his baptism in July.
Other than that, we have had to rely on Kensington Palace to release images so we can see his progress. Hopefully this year Louis will join his siblings on the Buckingham Palace balcony for the RAF flypast after the Trooping the Colour. He may also make an appearance at a polo match in the summer to cheer in his dad, Prince William.
Here are some of the cute images we have of little Louis.
As with millions of other families, the Cambridges will be busy this week organising their children for a return to school after the summer break.
Prince
George, 5, will be starting year one at Thomas's Battersea on Thursday.
Although he attended Reception last year and will keep the same
friends, George will have a new teacher and classroom as well as more
advanced work to adjust to.
Princess
Charlotte, 3, started at Willcocks Nursery School in Kensington in
January. She will return to her routine on Wednesday.
The royal youngsters have had a wonderful summer break with baby brother Louis and mum and dad Catherine and William.
The
family of five first celebrated Louis's baptism on 9th July and the following day the children watched the RAF Centenary flypast from a Buckingham Palace window while the adults stood on the balcony.
Mustique in the Caribbean was the venue for a beach holiday with their
grandparents Carole and Michael Middleton. It was here George celebrated
his birthday.
Then
the family spent a large amount of time at their country residence,
Amner Hall on the Sandringham Estate in Norfolk. Amner allows the
children to run and play in privacy as well as enjoy the property's
tennis court.
Towards
the end of the holiday the Duke and Duchess and children headed to
Balmoral Castle in Scotland to visit the Queen and Prince Philip. Here
George took part in his first grouse shoot which is quite a milestone
for a royal youngster.
All in all a lovely holiday before school begins again.
