- Plain posted a photo with the baby
- She and Meyer married in 2016
Palin shared the good news on Monday by posting a photo of the happy couple with their newborn on Instagram.
"Welcome to the world Atlee Bay," she wrote in the caption.
Proud grandmother Sarah Palin posted the same photo on her Facebook page, writing "The whole family couldn't be more thrilled."
'What a happy story! What a happy day," a story on Sarah Palin's site quotes her as saying.
Babies are the best ingredient in our world, and we're blessed to help welcome Atlee Bay to it. The whole family couldn't be more thrilled!'
Palin and Meyer, a Marine Corps vet, married in 2016 after calling off their engagement days before their 2015 wedding.
They are also the parents of a daughter, Sailor Grace, born in 2015. Palin had her oldest child, 8-year-old Tripp, with former fiancé Levi Johnston.
