Other photos show Vann alone with her two daughters, wearing a black suit and placing a hand on Nyla while carrying Zoë in her other arm. There’s also a sweet shot of Nyla giving her baby sister a kiss on the head.

In February 2023, the actress, who will soon star in the new Fox series DOC, celebrated Nyla’s second birthday with an adorable family photo on her Instagram.

Sitting in between her parents, Nyla is pictured getting kisses on both of her cheeks from both Oyeku and Vann as the actress took a moment to reflect on the special occasion.

“Happy 2nd Birthday to you, Nyla! My heart beats to the rhythm of your discoveries, the pace when you corre corre corre (run), the forte and piano discovery of your voice,” Vann wrote in her caption.

“You are life. You are love. God bless you mi vida! Mommy and daddy love you so much! #cumpleanosfeliz 💗🙏🏽💗 #okuojoibi.”
