12:56pm: Why Prince William and Kate always delay their baby announcement:

It's been almost five hours since Kensington Palace announced that the Duchess of Cambridge was in labour, and it could well be that she has already welcomed her third child, but is waiting to share the news with the world. When they welcomed their first two children, Prince William and Kate were able to enjoy the news for a few hours before announcing it to the world. They celebrated in private at the Lindo Wing in St Mary's Hospital, with William making the all-important calls to their closest family members. The Duke and Duchess tend to wait a few hours before making the official announcement, to allow them time to celebrate the birth in private and to tell their family.
