The Duke and Duchess of Cambridge presented their new daughter to the world last Saturday evening, just 10 hours after the birth of the baby.
The new baby is the fourth in line to the throne and the Queen fifth great grand-child. She will be the first to take the title of Princess for 25 years.
A girl has not been born this high up the line of succession in the UK for nearly 65 years, since Princess Anne was born.
