Matt Roloff proudly threw a birthday party for his grandson Jackson yesterday as the boy turned one year old.
The little person child of Matt and ex-wife Amy's dwarf son, Zach, and his regular-size wife, Tori, posed for a selfie with his grandpa on his birthday on Saturday, May 12.
The little boy was clutching a Frisbee and smiling at the camera as Matt held him up, beaming with joy. Jackson wore overalls and a tee shirt.
Behind the one-year-old in the photo, there was a tent decorated as "Camp Jackson" with many wrapped birthday gifts beside it.
Matt wrote as a caption, "Happy Birthday baby J. What an incredible day of celebrating your 1st year of life!"
Jackson's mom Tori also posted an Instagram photo, of Jackson sitting in front of his birthday cake with frosting all over his mouth.
Tori captioned it, "and somehow we have a one year old? Happy birthday Mister Mister. We love you more than you will ever know."
Radar reported yesterday that Jackson was turning one and Matt couldn't be happier.
Matt wrote as an Instagram caption to fans alongside a photo of Jackson on Friday night, "Getting everything ready for this little farmers one year birthday celebration tomorrow.... Like this if you want me to wish him a Bday wish from You!"
While Amy hasn't yet publicly Instagrammed about the occasion, the loving grandma will no doubt share her warm feelings about Jackson's birthday soon!
Chances are, the heartwarming party will also appear on a future episode of the Roloff family reality show, Little People, Big World on TLC.
Jackson has become a big attraction on the show as fans watch him grow.
The adorable tot was born with achondroplasia, a form of dwarfism, his dad revealed on a TLC blog. Amy, Matt, and Jackson's dad Zach are all also dwarfs. Although the baby was born at a healthy weight of 9 pounds, 1 ounce, and was 20.5 inches long, Jackson will be short in stature as he ages.
Jackson was born via c-section on May 12, 2017. He had a 50-50 chance of inheriting the dwarfism gene from Zach, as his wife Tori is a regular-sized person.
Devoted mom Tori told PEOPLE, "He's happy and healthy. That's all that matters."
