The couple confirmed to People that their son was born on Friday.
"Exactly one month before Emmy's 2nd birthday. the sun rose and they knew this day would be different", Meehleis said.
"Morgan's fingers grasped onto their son, who filled such empty arms", she continued. "Our baby girl, Emmy, passed away yesterday", Bode said in a statement back in June.
The Millers' tragedy came four months after they announced on Instagram that they were pregnant with their third child.
The birth comes in the wake of the June death of their daughter after she drowned in a pool in the Coto de Caza neighborhood of Orange County, California, on June 9 after she slipped away for a "short amount of time". Bode was not present at the time of the drowning but Morgan was just inside the friends home.
