Robert Irwin loves sharing adorable updates on Bindi Irwin and Chandler Powell's daughter Grace, and it looks like he's really taken to life as an uncle.
In July he shared two sweet photos to Instagram, and gushed over his adorable niece.
The pictures showed him cradling the three-month-old in his arms, Grace beaming out at the camera while Robert smiled.
"Uncle life is just the best ☺️ Look at Grace's little smile!!!!" he captioned the post with Bindi's daughter.
This isn't the first time the 17-year-old has voiced his love for little Grace either, sharing several photos since her arrival on March 25.
In May, Robert posted a black and white snap of Grace wrapped up in a beanie and blanket with the caption: "Look at my lil niece!!!! 😊"
Robert also shared a photo for Mother's Day, where he posed with his own mum Terri, as well as sister Bindi who was cradling Grace in her arms.
In April, Robert posted a one-month update on Grace with a closeup photo, as well as three professional portraits with the bub at Australia Zoo.
"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!" he wrote in the caption.
Grace also appeared in the photo Robert shared for National Siblings Day, where he honoured sister Bindi as a new mum.
And of course there was the now-iconic photo he posted the day after Grace was born, letting the world know the Irwin family had another little member.
He wrote alongside a photo of him cradling the newborn: "Let the uncle adventures begin! Love you so much, Grace ❤️"
It's pretty obvious that Robert adores his niece, and he's not the only Irwin who can't get enough of baby Grace.
Bindi shared a number of sweet Instagram updates on her daughter before announcing she'd be taking a break from social media in late June.
Her husband Chandler Powell had kept us up with the baby updates in her absence, regularly sharing the cutest snaps of their growing girl.
Most recently, Rob posted another candid snap with his favourite niece, and by the megawatt smile on her face, she's clearly just as smitten with him too.
The picture was taken at a campsite, and Uncle Rob is holding Grace in his lap while she looks at the camera.
In his caption, he spoke about their big day together and what the bub thought of their wild adventure.
"Hanging out with Grace in the camp after a big day catching crocs is the best 😊 She's lovin life up here on our crocodile research expedition!" he wrote.
Bindi was quick to respond by commenting, "The happiest face ❤️❤️❤️."
Grace was born on March 25, 2020, conveniently arriving on her parents' first wedding anniversary.
