She added, “You made your presence known when we would talk and sing to you while you were still in my tummy. You always responded to Mama, Dada, and Zion. From that moment, in those early days before you were born, I already knew how much I loved you.

“I love you, bubba Kai!!! Happy birthday, my little one!”

Sarah's partner, Richard Gutierrez also posted some highlights of their intimate birthday celebration with Baby Kai.

Sarah later clarified through a chat with a netizen that they decided for a simple event for their son since they are traveling soon.
