Little people, big hearts!

Fans have been overjoyed for Zach and Tori Roloff, who became first-time parents following the birth of their baby boy Jackson — check out the video below to see his first pictures — last Friday!

And it’s clear that the new parents are doing exactly what they were born to do! In a touching picture posted to Instagram, the kindergarten-teacher-turned-new-mom gushed, “My heart is so unbearably full. I’ve only spent four days with this little guy and I have fallen in love completely with him This is what I was meant to do. Mommy loves you, Jackson!”

There’s no denying that Zach, 27, is also totally over-the-moon.

“Jackson has already mastered holding daddy’s fingers and snuggling with mom,” the Little People, Big World star gushed in a video for TLC. “He is adorable and Tori and I are loving being parents.”

On the new season of LPBW, fans saw as Tori and Zach faced their anxieties about the possibility of Jackson being a little person. They first expressed concerns when it was revealed that his limbs were below average in size during pre-natal checkups — while they haven’t revealed whether or not he has dwarfism, he was born weighing in at 9 pounds, 1 ounce and measuring in at 20 inches long.

“I had to have leg straightening, so I had two casts on. Then I had to go back into surgery sophomore year of high school, they added screws to the leg,” Zach reflected during one episode of Little People, Big World. “So I’m not going to say, ‘Oh yea, man, I wish my kid had dwarfism! All those struggles he’s going to go through? Heck yeah!’ But I’m also not going to say, ‘I really hope [he’s] average height.’ Average-height kids have issues, too.”

No matter what comes their way, we know that Tori and Zach will continue to be the best parents!
