The Duke and Duchess of Cambridge's children are growing up fast, with Prince Louis reaching a new milestone earlier this year as he started at Willcocks Nursery School in Kensington.
The royal youngster, who also celebrated his third birthday in April, has had a slightly different upbringing to his older siblings, Prince George and Princess Charlotte.

Prince William and Kate reside at Apartment 1A in Kensington Palace, London, but until 2017, they had lived in two different places. Prince Louis, who was born in 2018, is therefore the only one of their children who has lived in London the majority of his whole life.
From 2010 to 2013, the couple lived in Anglesey, an island off the north-west coast of Wales, where William worked as an RAF search and rescue pilot. Prince George was born in July 2013 and the Cambridges relocated to their Norfolk country estate, Anmer Hall, after William transferred to the East Anglia Air Ambulance.

The Cambridges live at Kensington Palace
Princess Charlotte arrived in May 2015 and Kate captured photos of their newborn daughter as they settled into life as a family-of-four at Anmer Hall. Prince George started his education in Norfolk in January 2016, attending Westacre Montessori School Nursery.
The Cambridges continued living at their country estate, which was a wedding gift from the Queen, until William carried out his last shift with East Anglia Air Ambulance in July 2017.

Anmer Hall in Norfolk
The family made a permanent move to Kensington Palace in time for Prince George to start school at Thomas's Battersea. Unfortunately, Kate was suffering from hyperemesis gravidarum (severe morning sickness) during her third pregnancy with Prince Louis and was unable to accompany her son on his first day at school.
William and Kate have maintained their Anmer Hall residence and tend to spend weekends, school holidays and Christmas at their Norfolk home.
