Bucklebury's not the only place for a party tonight, there's one happening 30 miles along the road at the aptly named Duchess of Cambridge pub in Windsor, the only pub in the country with that name.
It got underway at midday so there are some very happy people in the Royal borough. There with them - Sharon Thomas who meets Will Calvert of Windsor & Eton brewery and Daniel Park of the Duchess of Cambridge pub.
The Duke and Duchess of Cambridge proudly showed the world their baby son, a future king, before taking him home tonight.
We look back at Kate's journey since early December 2012 when it became public knowledge that a royal baby was on its way.
