In September, Mayer, 40, announced that she was expecting the twin girls with her husband. At the time of the announcement, Mayer explained on Tumblr that she would take "limited time away" from work after giving birth.

"Since my pregnancy has been healthy and uncomplicated and since this is a unique time in Yahoo's transformation, I plan to approach the pregnancy and delivery as I did with my son three years ago, taking limited time away and working throughout," she went on to explain. "I've shared the news and my plans with Yahoo's board of directors and my executive team, and they are incredibly supportive and happy for me. I want to thank them for all of their encouragement as well as their offers of help and continued support."

After giving birth to her first child, Mayer worked through her two-week maternity leave, leading many to question the demands placed upon working mothers.
In April 2013, Mayer overhauled Yahoo's parental leave policies, granting mothers up to 16 weeks of paid leave with benefits, and up to 8 weeks for new fathers.
Yahoo made headlines earlier this month after reports that its board was weighing a sale of the company's core Internet business, which Mayer had failed to turn around after more than three years as CEO.
Mayer's announcement comes a little more than a week after Facebook's Mark Zuckerberg and Priscilla Chan shared the news of the birth of daughter Max.
