The birth of a new heir to the throne has been breathlessly anticipated since William and Kate wed on April 29, 2011, in a lavish ceremony at Westminster Abbey.
When news of a royal pregnancy was announced, there was rejoicing in many households in Britain and throughout the world.
Despite a rough start to the pregnancy, when she was hospitalized for acute morning sickness, the 31-year-old Kate made a number of public appearances that were halted only near the end of her term.
Since the duchess has cut back on her royal duties, media outlets have been clamoring for position outside of the hospital in anticipation of the birth, jockeying to secure the best vantage point for filming William and Kate emerging, babe in arms.
Officials have said that William plans to take two weeks' paternity leave and then return to his military duties as a search-and-rescue helicopter pilot in Wales.
