Kirstin Czernek always wanted a big family — though she didn’t necessarily always envision the one she has now.

The gym-owner-turned-influencer, who usesTikTokandInstagramto share the story of her growing family and her journey to adopt a child with Down syndrome, initially planned on having three kids with her husband, Tomas.

Today, she has four — one biological child and three adopted from foster care — and two of her children have Down syndrome. And even with the challenges, the couple might eventually make room for more.

“My husband now wants five,” Kirstin, 37, tells PEOPLE with a laugh. “I’m working my way there.”

The couple’s journey to building their family began six years ago, when they adopted Mia, now 8 years old.

“She’s how we started our family,” Kirstin says. “We adopted her from foster care when she was 18 months old. While getting placed with her, we were told that her mom was pregnant and they asked if we were willing to adopt both of them.”

Mia’s brother, Kai (now aged 6) was born six weeks later.

“I found out about her Down syndrome diagnosis when I was 20 weeks pregnant,” Kirstin says. “It was something that had never crossed my mind. I was young, I was 29. It wasn’t even on my radar.”

Kirstin says she took the remainder of her pregnancy “to grieve the child I thought I was going to have.”

The moment her child was born, though, everything changed.

“I fell instantly in love and it opened my eyes to the Down syndrome community as a whole,” she says.

The addition of Aria, now 5, to the family changed everything.

“I thought we were going to land at three and once we had Aria, I felt like, I don’t think we’re done. I don’t feel like our family’s complete yet,” Kirstin says.

She continues: “Aria loves with everything in her. Everything she does is exaggerated. A jump, a smile, a laugh … That turns off in most of us. We stop living so big as we age. We tone down. Individuals with Down syndrome, they don’t tone down. Everything is big, everything is special.”

When Aria turned three, Kirstin says the couple began to pray about their next steps and decided on adopting another child — this time, one with Down syndrome, like Aria.

The couple worked with the National Down Syndrome Adoptive Network, which pairs families interested in adopting with agencies that can facilitate the process. They were added to a waiting list, where they sat for two years before Tomas got a message on Instagram.

Luca was born limp and barely breathing, with a hole in his heart and pulmonary hypertension and transferred from a small hospital in Alabama to a larger facility, where he was put on life support for 10 days.

After two months, he turned a corner and on Jan. 10, 2024, he came home.

Now 5 months old, Luca is the perfect addition to the family, Kirstin says.

“It is hard, I’m not going to sugar coat it,” she says. “Medically, it can be very difficult. But the positives and the things I get to experience with both of them on a day to day basis … it’s such a beautiful, full life that, until you have it, you don’t realize, ‘Oh, this existed.’ "

“After Aria’s diagnosis, I would read things online about Down syndrome and everything was so negative,” she says. “When I had the opportunity to show a different side — one that was real — it made sense to me.”

She continues: “Now, I have so many conversations with moms who are pregnant with a child with Down syndrome and they’re terrified. And they’ll message me and say, ‘I’m not scared anymore. I’m excited after watching your experience.’ That makes it worth it for me.”

And while she acknowledges that she might not publicly document so much of her day-to-day as her children get older, Kirstin says she hopes she’s able to showcase the beauty of the Down syndrome community — and the unbridled joy that her children experience, and bring to her own life.

“Having a child with Down syndrome is like living in a castle,” she tells PEOPLE. “Like you’ve been given this amazing, beautiful, castle. Not many get to live in a castle and it’s not always a fairy tale. There’s more responsibility — castles are old, things break down, everything about it is more delicate. But at the end of the day, you get to live in a castle. You get an experience that no one else does.”
