Zach and Tori Roloff's son Jackson Kyle has officially started preschool.
On Wednesday, Tori, 29, announced her son's exciting milestone moment, sharing a photograph of Jackson, 3½, on Instagram.
The Little People, Big World star detailed the experience of her son's first day in the caption of her post, writing, "It's fine. I'm fine. My sweet baby J had his first day of school today!"
"He's been asking for so long to go to school and he finally got to go today!" she continued. "My mama heart was bursting with pride watching him March in like he owned the place."
"He gave me a big hug and kiss before I left and said 'peace mom!' ✌🏼. I love this kid so stinking much!! So proud of you Jackson! ❤️," she added, also writing the hashtags, "#babyjroloff" and "#timeisathief."

In the comments section of her post, a group of fans shared their excitement alongside Tori that her little one would be embarking on his first day of school.
"Look at that smile !!!!! He is so proud !! ❤️❤️❤️❤️❤️❤️❤️," one user wrote as another added, "He looks so excited 😍."
Last summer, Tori got candid in a social media post, sharing a message for people giving her unsolicited parenting advice tied to a picture she posted of Jackson.
While the mother of two did not specifically call out what remarks she was responding to, if any, she did reply to an Instagram user one week earlier who left a comment of "concern" on a family photo posted for the Fourth of July.
Tori noted that she recognizes that it is her "privilege to have a platform where I can share information on things I find important like dwarfism or a pandemic or other global issues."
"I did not chose to be in the public eye. I fell in love and I chose my husband then and I choose him every day since," she wrote of Zach, who, like their children, has achondroplasia. "This all comes along with him and our family and I feel like I've done a damn good job of being the best I can be."
"I don't owe you anything. You don't own me. You can't manipulate me. This is my instagram and I can choose what I want to share," Tori added. "If this doesn't sit well with you … I'm sorry. It's not my job to change your mind. ✌🏼"
