It was a milestone moment for Prince Louis as he finally joined his older brother and sister for his first day at school.
The four-year-old looked smart in his school uniform as he embarked on his first day at Lambrook School in Berkshire yesterday and was dropped off by his parents the Duke and Duchess of Cambridge. Like all parents, his proud mum and dad may have been apprehensive about how their youngest child would be feeling about his new start. But it appeared he did not need any encouragement at all - not least from his dad Prince William.
