Alexandra Reeve Givens and Garren Givens have welcomed their first child.

Born on Saturday, June 13, in Washington, D.C., son Christopher Russel Reeve Givens weighed in at 8 lbs., 3 oz.

“He was named after his grandfathers on each side, two very important role models for Garren and Alexandra,” a representative of the family tells PEOPLE.

“The entire family is thriving during their first few weeks home,” according to the rep.

In keeping with his late grandfather, actor and activist Christopher Reeve, and the rest of the Reeve family, the new addition is already suiting up — in a “Team Reeve in training” T-shirt — to support the work of the Christopher and Dana Reeve Foundation.

Last October, the foundation announced a huge breakthrough in the treatment of spinal cord injuries.

Alexandra, 31, the daughter of Christopher Reeve and Gae Exton, serves as a senior counsel in the United States Senate and an adjunct professor at her alma mater, Columbia Law School.

Garren, 33, works in the Obama administration as the director of the Presidential Innovation Fellows program.

The couple met while both were studying at Yale University and married in 2008.
