He added to ET of baby Grace, "She's at that age now where she's really reacting to things, you know, when she sees a new animal. We met a koala for the first time the other day and her little face, she was all kinds of sleepy, and she saw that koala and her face just lit up. The biggest smile, and it was amazing. I can already tell she is a wildlife warrior. And I cannot wait to just introduce her to everything zoo life."

Back in April, Robert wrote on Instagram, "Being Grace's uncle is awesome!! I can't wait to watch this little warrior grow up and take on the world - I reckon she'll be running the zoo in no time!"

"I feel so honoured that I'll get to share all the amazing experiences that I had growing up in a zoo, and teach her about everything from rescuing wildlife to caring for our family of animals!" he added.

New mom Bindi, 22, recently discussed her excitement of wanting to focus on the "extraordinary" bond that she's already created with her newborn. "When we first got her home, it's as if she's always been with us," she told PEOPLE. "It's a really strange feeling when you can't remember what your life was like before this beautiful little person. I never knew love like this before."
