Facebook set up a petting zoo, giant Lego stations, and a robotics exhibit for hundreds of kids on its campus

A petting zoo, drone tutorial, cupcake decorating station, and multiple Lego stations were just a few of the activities the company set up for its employees' offspring to enjoy.

"Facebook's mission to make the world more open and connected, and its values - to be bold, be open and move fast - can be shared by everyone, children and grownups alike," Lori Goler, Facebook's VP of Human Resources, said. "The event is intended to inspire and educate."

Facebook offers several benefits for families, including a four-month paid leave for new moms and dads and a $4,000 bonus for each child born or adopted.

The company also covers costs for egg and sperm donation, egg freezing, and other fees related to surrogacy and in vitro fertilization.
