Nia Sanchez and Danny Booko are officially the parents of four kids under 4.

The former pageant queen announced she gave birth to her and the actor’s fourth baby, a girl whom they’ve named Adelaide, on Thursday, per Us Weekly. The little one joins the couple’s other children: Asher, 3, and twins Zariah and Isabelle, 23 months.

“The first moments with baby No. 4 felt so sweet and intimate,” Sanchez told the outlet.

“In our previous birth experiences, we’ve had a lot more people in the room. And we’ve always had a doula. This time, it was just us with our doctor and two nurses. This birth was extra special because Danny was able to deliver the baby.”

The “Valley” co-stars wed in 2015 and started trying to conceive four years later — only to face “ups and downs, so many tears and unanswered questions.”

The duo underwent three failed rounds of intrauterine insemination and were about to start IVF when they found out they had a baby on the way, Sanchez explained via Instagram in June 2021.

Asher arrived in November of that year, and he became a big brother in June 2023 when his sisters arrived.

Sanchez, 35, revealed to Us Weekly in December 2024 that she was pregnant again “a little bit earlier” than planned.

“We figured this baby needed to come at a certain time,” she noted. “I think we’re just gonna go for a football team.”

Sanchez made it clear to her Instagram followers in April that the pregnancy was her last, adding that she was “trying to soak up” each moment.

She and Booko, 41, repeatedly discussed their family plans on Season 2 of “The Valley.”

Booko asked his partner to “quit telling people you want to have another baby right now” in an April episode.

She replied, “I would have got pregnant months ago. You wouldn’t let me. … I don’t want to wait five years to have another kid and then try to get my body back. I want to have one more and be done and be able to, like, have my body to myself.”

Booko, after quipping that Sanchez had been “trying to leg-lock” him in the bedroom, pointed out, “I just had to get a storage unit because we’re bursting at the seams. My son does not have his own room.”

The former model alum requested their family relocate to Santa Clarita, Calif.

That same month, Sanchez confirmed to the “Daily Dish” that they were in fact moving there in order to better fit “all of [their] 17 children.”

She gushed, “We will have more space, which is very exciting.”
