Introducing their new little girl to the world, the couple posted a sweet photo of their two older kids holding Esti in their arms on Jan. 19. "She's here!" Chrissy wrote on Instagram. "Esti Maxine Stephens - the house is bustling and our family could not be happier."
She continued, "Daddy sheds nightly tears of joy seeing Luna and Miles so full of love, and I am learning you still need diapers with a c section!? We are in bliss. Thank you for all the love and well wishes - we feel it all!"
"I'm in awe of Chrissy's strength and resilience and I'm so thrilled to see how Luna and Miles embrace their baby sister," he added. "I'm so, so grateful, but that doesn't seem like a big enough word."
