Case closed: It’s a girl!

NCIS: Los Angeles star Daniela Ruah and David Olsen welcomed their second child, daughter Sierra Esther Ruah Olsen, on Sunday, Sept. 4, she announced Wednesday on Instagram.

“Apparently she thought Labor Day weekend meant LABOR day weekend… Look who showed up three weeks early! On Sept. 4th we welcomed little Miss Sierra Esther Ruah Olsen,” the actress captioned a family photo.

“She entered the world in her own way — breeched! I was a good candidate to deliver her naturally so I needed to find a doctor in L.A. who would know how to do it. Fortunately I found one of the few… Healthy & happy mommy & baby walked out of the hospital 24hrs later. I had an OB and doula assisted birth at Cedars-Sinai, and the #love and #support of my wonderful #hubby This photo is the perfect representation of everything I’ve ever wanted.”

Sierra weighed in at 7 lbs. and measures 20.8 inches long, her rep tells PEOPLE.

Ruah — who broke her pregnancy news on the social media app in April — and Olsen also share son River Isaac, 2½.

No dia 4 de Setembro demos as boas vindas à menina Sierra Esther Ruah Olsen! Deu entrada no mundo da sua própria maneira- de apresentação pélvica! Eu era boa candidata para dar à luz naturalmente nesta situação e por isso tive de encontrar um médico em Los Angeles que ainda o soubesse fazer. Felizmente encontrei um dos poucos… Mamã e bebé saíram do hospital saudáveis e felizes 24 horas depois. Foi um parto assistido por um obestetra e uma doula no Cedars Sinai, e o amor e apoio do meu maridão ❤️ Esta foto representa tudo o que sempre quis. #Família #Exaustamasfelizdavida #ODireitodeescolhadamã

The happy parents met on the set of NCIS: Los Angeles, on which the 32-year-old plays Special Agent Kensi Blye. Olsen, a former Navy SEAL, has acted as his younger brother Eric Christian Olsen‘s stunt double in the past. Eric’s own wife, Sarah Wright Olsen, also gave birth to a baby girl this summer. The couple welcomed Esmé Olivia on Aug. 9.

My Best Advice: Moms Share the Tips They Wish They Knew Before Kids

Ruah’s pregnancy comes after heartbreak: she experienced a miscarriage last October at nine weeks along.

“Something like that hits you physically, emotionally and psychologically, but my doctor said, ‘Even if you sat on my table the whole time, this still would’ve happened. You have to try again,’ ” Ruah told Fit Pregnancy and Baby for the magazine’s September cover story.

That “second try,” was when the pair conceived their little girl.

She said, “Nature is a beautiful thing — it does what it needs to do when it needs to do it.”

How inspiring to hear of a mama who trusted her body and how sad that doctors are losing the skillset to support normal variations in childbirth.
