Britain's royal baby watch may be reaching a fever pitch, but Prince William isn't one to sit tight and wait for news.


Many in the British press have predicted that the first child of the prince and his wife Catharine Middleton is expected to arrive on Sunday. Dozens of photographers and cameramen remain on royal baby watch outside St. Mary's Hospital in London.



Bookmaker William Hill says most people are betting money on a royal birth Sunday, Monday or Tuesday.


But the prince enjoyed a game of polo against his brother Prince Harry at a charity event on Sunday.


The birth, when it does come, will be announced by a bulletin posted on an easel outside Buckingham Palace.


The news also will go out on Twitter from the palace.
