Bristol Palin gave birth to her second child, Sailor Grace, on Wednesday. The 25-year-old daughter of Sarah Palin announced the news on her Instagram account on Christmas Eve with an adorable photo of her newborn daughter.

“My sweet Sailor Grace was born yesterday, our family couldn’t be more complete,” she captioned the photo.

She also shared an Instagram photo of her son, Tripp, who turns 7 years old this month, welcoming his sister into the world.

“My heart just doubled,” read the caption.

Palin announced her pregnancy in June, one month after ending her engagement to Dakota Meyer. In a blog post, the “Dancing with the Stars” alum told her followers she has tried her “hardest to keep [her] chin up,” despite the tabloid fodder surrounding her broken engagement.

“I know this has been, and will be, a huge disappointment to my family, to my close friends, and to many of you,” she wrote. “But please respect Tripp’s and my privacy during this time. I do not want any lectures and I do not want any sympathy. My little family always has, and always will come first. Tripp, this new baby, and I will all be fine, because God is merciful.”

Despite the rocky start, Bristol has said she could not be happier with her growing family. In November she posted this snap with the caption, “Happy Thanksgiving .. thankful for my babies.”

Welcome to the world, baby Sailor Grace!
