Daniela went on to share that the birth wasn’t easy but that the pair were both doing well.

Apparently she thought Labor Day weekend meant LABOR day weekend... Look who showed up 3 weeks early! On September 4th we welcomed little Miss Sierra Esther Ruah Olsen! 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 LA 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. #Family #ExhaustedbuthighonLife #Amothersrighttochoose #InformedBirth @binibirth --- Pelos vistos ela achou que o Dia do Trabalhador (nos EUA) significava dia do TRABALHO DE PARTO... Olha quem decidiu aparecer com 3 semanas de antecedência! 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
