Pregnant woman 'twitters' birth

A woman from Florida was the first to webcast the birth of her child

The wife of one of the co-founders of Twitter is keeping family and friends up to date with the birth of her child using the micro-blogging service.

"Dear Twitter, My water broke. It wasn't like Charlotte in Sex and the City," Sara Morishige Williams, or @sara as she is known, wrote on Monday.

Updates follow her into hospital and through her contractions - which she timed using an Apple iPhone, she said.

Her last update asked for an epidural to be administered.

The father-to-be, Evan Williams, has not followed his wife's lead by "tweeting" the birth.

It is not the first birth to be followed in real-time online.

In 1998 a woman from Florida was the first to webcast the birth of her child.
