Ashley Graham celebrates her twin sons' second birthdays.

Ashley Graham's twins are celebrating another year around the sun.

On Sunday, the model, 36, shared a carousel of photos on her Instagram in celebration of twin sons Roman and Malachi's second birthday. In one photo, the toddlers adorably stand next to each other in graphic long-sleeve shirts and diapers, drinking out of cups and covering their faces for the camera.

In another, the brothers wear dinosaur masks and capes as they stand on a fuzzy couch.

"Two years old, X 2!! Happy Birthday to our sons, Roman and Malachi!" the proud mom wrote in her caption. "You may share a birthday but you two couldn’t be more uniquely different. Cheers to another year of growth, play, and learning!!!"

Alongside her twins, Graham is also mom to son Isaac, 3, whom she shares with husband Justin Ervin.

In September, the mom of three spoke with PEOPLE about how a flight cancellation from Los Angeles to New York City caused panic when she realized she wouldn't be able to get back to see her sons.

“I started crying. I knew I only had one day to see [my kids]. And as a mom, when you're planning out your time to see your children, every minute matters.”

Though Graham was supposed to attend the U.S. Open when she returned home, she said she ended up canceling her plans to stay home with her boys.

“It's little tiny sacrifices you make,” she said. “I would've loved to have seen Coco [Gauff] win in person, but we can always watch on TV,” she continues.

She also shared that having three kids has been hard to manage at times.

“They're so different,” she said of her twins. “I tell them all the time, you're just brothers born at the same time. You're not twins. They're just not alike. So I've got three very distinct different personalities in the home.”

“It's a lot. I'm juggling them and my career and being married," she added. "And it's like every day you just have to pray and have your peace and then you can get through it.”
