Earlier this month, Bindi Irwin, the 22 year-old daughter of the late “Crocodile Hunter” Steve Irwin, announced that she would be taking a break from social media after giving birth to her daughter Grace Warrior. Now, her younger brother Robert has broken his silence about her social media break.

“She’s just the most kind, just genuine person that you’ll ever meet and now to see her as a mom, it’s just amazing,” Robert, 17, told Entertainment Tonight. “She is such a good mom and she’s really tried to now prioritize just time with family.”

“She’s taking time out with, of course, Chandler, her husband, and her beautiful daughter, Grace, and so me being an uncle getting to be in there and be involved, it’s just amazing and I never thought I’d see my big sister as a mom,” he added. “It’s just a really surreal and wonderful experience and to have a new family member is just awesome.”

Robert went on to say that as Grace’s uncle, he’s introducing her to as many new things as possible.

“She’s at that age now where she’s really reacting to things, you know, when she sees a new animal,” he said. “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,” Robert continued. “And I cannot wait to just introduce her to everything zoo life.”

More than anything, Robert wants to be a fun uncle to Grace.

“I’m already trying to teach her how to play the guitar,” he said. “It’s one of my passions so she’ll always go to sleep when I play the guitar. She loves it, so, you know, I’m trying to be the fun Uncle Robert.”

Robert will also be appearing on Discovery Channel’s popular Shark Week, and he opened up about what it was like to take part in a shark dive.

“Well, I think that for me, this adventure, it was probably the most amazing trip I think I’ve ever been on, you know, for so many reasons,” he said. “I got to actually swim with sharks and have them [very close] to my head to see how similar they are. It was the biggest adrenaline rush and an amazing experience, and I cannot wait for you guys to see it.”

Robert added that he had to learn how to keep calm around the sharks since they could sense a person’s heart rate.

“But the problem wasn’t the fear factor, it wasn’t that my heart’s going crazy out of fear, it’s more that my heart was going so fast out of pure joy and excitement, you know?” he explained. “I was so excited to see sharks firsthand. I wanted to just get as close as possible. And so, working with shark experts Paul de Gelder … these amazing people that have always worked with sharks their whole life … they really taught me you almost have to go into this kind of zen state. You have to just sort of calm down — which is hard for me, because my adrenaline’s through the roof — sit, watch and just try to kind of take it all in.”

“Easier said than done when there’s a shark coming at ya,” Robert concluded. “But I think, as I progress, I like to think I’ve really become more at one with these animals. I feel like now, and only now, I’m at the point where I reckon I’m getting pretty good with sharks.”
