The couple welcomed their first child after nearly a decade of marriage on October 1, completing Heidi's longtime dream of becoming a mama. "What a blessed journey pregnancy has been," she wrote on Instagram days before the birth. "It's hard to believe in such a short time I will be holding my son! I have been dreaming of this my whole life. Precious little miracle. So filled with love."

While the cherub's moniker isn't usual, dad Spencer wanted something even more "flashy." "We came to a common ground," Spencer explained to E!'s Zuri Hall in August. "I definitely wanted Speidi. At least a middle name!"

As they told Us Weekly, the baby's final name was sports-inspired. "He'll probably be a pitcher, so when Gunner steps to the mound, he's going to be gunning those throws down home plate," Pratt told the magazine. "If he wants to be a skier, he's going to be gunning down those moguls. It just applies to a lot of sports."
