The royal baby was taken to see his grandparents on his first afternoon out today as it was revealed the Queen and Prince Harry have now met Baby Cambridge for the first time.
Kate Middleton and Prince William smiled broadly and waved from their car as they were driven away from Kensington Palace by security, where they had spent their first night together as a family.
The royal couple looked happy and fresh-faced, with Prince William sitting in the front passenger seat and Kate Middleton in the back with their child in his baby seat.
They left their west London home shortly after the Queen had visited her new great-grandson and potentially discussed names with the parents, as the guessing game over what he will be called continues.
Kensington Palace officials would not confirm where the young family were going this afternoon, but their black Land Rover was later seen arriving at grandparents Carole and Michael Middleton’s mansion in Bucklebury, Berkshire.
The Queen, who will travel to Balmoral for her summer holiday on Friday, spent 30 minutes with the Duke, Duchess and Baby Cambridge from 11am.
It has also emerged that Prince Harry, who is said to be thrilled to have become an uncle, may have been there last night after the trio left hospital, having raced back to London from Wattisham airbase in Suffolk where he is on duty with the RAF.
It is understood that James Middleton and Pippa Middleton were also at Kensington Palace yesterday evening.
Prince Philip has yet to meet the child, but he and the Queen will be heading to Balmoral on Friday and it is understood that Kate Middleton and Prince William may take the royal baby there for a long weekend this summer.
