Today show weekend anchor Jenna Wolfe and partner Stephanie Gosk on Wednesday welcomed their second child.

“Quinn Lily Wolfeld-Gosk born at 4:06 6lbs 12ozs Everyone is great,” Gosk captioned a photo of Quinn. “Woohoo!!”

“It's time!!!” Wolfe tweeted as she went into labor, then added later in the day: “This little one's as stubborn as her mama (me). Apparently she's going to come out when she's good and ready.”

Wolfe, 40, made headlines when she announced she was expecting her first child with Gosk, an NBC News correspondent. Daughter Harper Estelle is now 17 months.

She announced her second pregnancy in August during a Today segment on creative baby announcements.

“This is an interesting one,” she said of an ultrasound to her co-hosts. “Does that face look familiar?”

“Does it look anything like that?” she asked, pointing to a photo of her daughter. “Harper is going to be a big sister!”
