Odette Annable and Dave Annable’s rainbow baby arrived on Oct. 13.

“Please give a warm welcome to the little lady that has completed our family and stolen all of our hearts,” the actress captioned her daughter Andersen’s Instagram debut Tuesday.

“You came into this world … fast and furious in about 2 hours door to door,” she continued. “Drowning in your sweetness and soaking up every bit of this beautiful time in our lives.”

Dave posted hospital pictures of his own, writing, “The next chapter has begun and we couldn’t be more grateful.”

Odette, 37, previously suffered three pregnancy losses before telling her Instagram followers in May that she was expecting again.

“It’s been a very long journey to get here, but we are here and we are thrilled and couldn’t be more grateful,” she captioned her reveal.

“A new chapter begins,” Odette went on to write. “A very special Mother’s Day indeed.”

In the “House” alum’s black-and-white social media upload, she and Dave, 42, told their 7-year-old daughter, Charlie, about her upcoming big sister status.

“Now I get my own baby!” the little one exclaimed before hugging her parents and thanking them.

Dave shared the same footage, writing, “I guess it’s not traditional to give your kid a gift on Mother’s Day. *Exceptions do apply. What a beautiful way to celebrate @odetteannable, the soon to be mama of two. We certainly know Charlie is excited.”

The “Brothers & Sisters” alum continued documenting his wife’s pregnancy via Instagram, from ultrasound updates to baby bump photos.

While celebrating Father’s Day in June, Dave posted a picture of Charlie holding a sonogram shot with a smile.

“There is no Father’s Day gift that can touch this feeling,” the actor captioned the sweet snap.

Dave and Odette, who separated in 2019 and reconciled within a year, became parents in 2015. The “Supergirl” alum suffered two miscarriages after Charlie’s birth and another last year.

“I was 15 weeks pregnant when this photo was taken back in December and today would have been your due date,” she wrote alongside throwback baby bump shots in June 2021. “There was another plan and our baby is no longer with us.”

The Los Angeles native went on to call Dave her “unwavering … rock,” gushing, “This experience has given me a new appreciation for my husband.”

Odette concluded with a shout-out to their “miracle” daughter: “I am so grateful for my family.”
