Despite her young age, Charlotte is already settling into a lifetime of royal duties.
She'll be attending The Willcocks Nursery School, a program that is very close to Kensington Palace and describes itself as a "traditional nursery school which strives to maintain its ethos for high standards, excellence and good manners".
"They thought it would be an ideal first step for Charlotte's education and they were impressed by the team who work there", said a Kensington Palace spokeswoman.
The Queen was homeschooled at Buckingham Palace by private tutors and teachers, so she doesn't have first day portraits like her children, grandchildren, or great-grandchildren do.
It is not the first time that pregnant Kate, 36 on Tuesday, has taken official photographs herself.
Charlotte is fourth-in-line to the British throne behind her father, her elder brother George and grandfather Prince Charles and her parents are expecting a third baby in April.
Founded in 1964, the "traditional" nursery was rated as "outstanding" by United Kingdom government education body Ofsted when it was last inspected in 2012.
PRINCESS Charlotte has started nursery school, with her mother Catherine the Duchess of Cambridge photographing her beaming as she headed off to school on a freezing London winter's day.
"We look forward to welcoming Charlotte to our nursery".
Charlotte will be full-time at Willcocks, at a cost of more than $AUD5000 per week.
