"It's no joke! Steph and I are having a BABY! For Steph's privacy and for health reasons we wanted to keep this stuff off the internet until now, but we're finally ready to share the news with all of you! This channel is a huge part of my life, so it seemed wrong not to share this huge news with all of you who have been there to support me in so many ways over the years.
We're so excited to be welcoming our newest Little Theorist into the world THIS SUMMER!"
"BabyPat" is the fan-given nickname of MatPat and Stephanie's currently unborn and unnamed son. Near the end of the March 13, 2018 live stream, it was revealed that the baby is due to be born on July 4, 2018.
