Twitter CEO, Wife Tweet About Baby, Labor, Delivery

Twitter CEO Evan Williams (@ev) and wife Sara Morishige (@sara) just welcomed a baby boy and, naturally, tracked the delivery — from water-break to birth announcement — on Twitter.

"Dear Twitter, My water broke. It wasn't like Charlotte in Sex and the City. Now, timing contractions on an iPhone app," Sara tweeted late Monday from her cell phone.

"The Contraction Tracker was fun until the contractions got painful," she followed up.

Later, she'd announce that she was admitted to the hospital and say, "Epidural, yes please."

It was her husband, though, who announced the baby's birth Tuesday afternoon.

"Yes! @sara gave birth to a perfect baby boy. Both are well. 8 pounds, 21 inches! Smiles all around," Evan texted.
