On June 17, 2015, the couple posted an update on their blog, saying;
"Baby Seewald is growing steadily and Mommy has been feeling some little, yet strong, kicks! We recently had an ultrasound, but aren't revealing our firstborn's gender yet. Can't wait to welcome this blessing from God into the world!"
The couple teased the gender of their child many times across social media, even including a poll where fans could vote on what they thought the baby would be, but ultimately they did not announce the gender before the child's birth.
On November 5, 2015, Jessa gave birth to her first child, a son. He weighed 9 pounds and 11 ounces and was 21 ½ inches long.
On November 11, 2015, Ben and Jessa announced that they had named their son Spurgeon Elliot Seewald. Spurgeon's first name was in honor of Charles Spurgeon, a nineteenth century British preacher. His middle name was in honor of late missionaries Jim and Elisabeth Elliot. "One guy that has really impacted my life is a great preacher of the past, Charles Haddon Spurgeon," Ben said when announcing his son's name. Jessa added, "We want to give him a strong name, with a lot of meaning.".
