Bindi Irwin’s Childhood Photo with Brother Robert Reminds Us That Sibling Love Is Unlike Any Other

Sibling love is one of the most special forms of love. Who else can you hold a years-long grudge over who really won Disney trivia — or who will roll their eyes over the totally cancellable thing your uncle just said at the Thanksgiving table? They may annoy you, but you can never stay mad for long (mostly because you have too much gossip you have to share!). The late Steve Irwin and Terri Irwin’s kids Bindi, 25, and Robert, 20, have a love like that. Bindi shared an adorable throwback photo of her and her little bro for his birthday today, and if you’ve been on the fence about having baby number 2, consider this your sign!

The Australia Zoo conservationist posted a flashback photo of her and Robert when they were 10 and 5. Blonde-headed Robert is wearing a tiger t-shirt that reads “Bindi” on the front. His hands are tucked into khaki pants as he casually stands next to his older sister. She’s also wearing a “Bindi” shirt, this one with blue-and-white stripes, paired with a denim skirt and boots. Her dark brown hair is braided on one side, and she wears matching bangs with her brother. Her arm is resting over the top of his head as they both smile in the adorable picture.

Text that reads, “Fast forward 15 years later,” pops on the screen, and then the picture changes to a current one of grown-up Bindi and Robert. Her hands are resting on his shoulders and he stands proudly almost a foot taller than her.

“Now I’m standing on my tiptoes to take a photo with you,” she captioned the heartwarming post, set to “Call Your Sister” by Taylor Edwards.

“Happy birthday to the best. 20 years, and a lifetime of adventures ahead of you – remember, you can always call your sister,” she added. “Love you @robertirwinphotography.”

We’re not crying, you are! OK, we’re crying too because that is the sweetest post we’ve ever seen. Little brothers might get a bad rep, but not in this family. Their fierce love for each other is unmatched, and it’s exactly the kind of relationship any parent would hope for their kids to have.

“Aw this is the BEST ☺️💙 Love you Bindi!!! Bring on the next 20 🎉,” Robert commented on Bindi’s post. His girlfriend Rorie Buckey wrote, “This is the best Bindi! ❤️🥰”

Another person commented, “You two are fab. Your dad would be so bloody proud. Happy birthday. 🎂🎉❤️.”

On Bindi’s birthday in July, Robert shared a different childhood picture of the two of them in a boat with a crocodile nearby. “Happy birthday @bindisueirwin ☺️❤️,” he captioned it. “Thank you for being the best big sister, and someone who I will always look up. I love you!”

These two are #SiblingGoals, for sure.
