Jon posted an Instagram of Hannah and Collin about to start their first day of junior year, posing together in front of two cars. “First day of 11th Grade!!!!” Jon wrote in the caption. “Good Luck Hannah and Collin!!! Love Dad.” Many people in the comments wrote that they can’t believe it, because they remember spending so much time with them as little kids, thanks to the show. “Wow 11th grade I remember watching them in diapers,” wrote one follower.ae0fcc31ae342fd3a1346ebb1f342fcb Hannah and Collin live with Jon, while the other children live with Kate. Jon commented on the arrangement in 2018, telling People that while he has a strong connection with Hannah and Collin, his other children don’t speak to him. “It’s what the kids want to do,” he said. “If they don’t want to talk to me, that’s fine, as long as they keep up with their sibling connections.” Kate does not post on Instagram often, but she has shared a few photos of the kids over the years. Most recently, she posted a photo of Aaden in July 2020 of him celebrating getting his braces off with some cake and candy. “Braces are a thing of the past in this house! FINALLY!” she wrote in the caption. “Yay us! #LastBracesOffParty #AadenIsBracesFree.” For more celebrity news delivered right to your inbox, sign up for our daily newsletter.

In a video from earlier this month, her siblings and her mom go on a shopping trip and out for ice cream. In another video, Mady shared some time spent outdoors with a couple of her siblings. In the caption she wrote, “sometimes i forget that i like the outdoors.” Jon and Kate’s two older daughters, twins Mady and Cara, are in college. They both attend school in New York, but are at different universities. “It is the biggest mixed bag of emotions and stress I have ever faced,” Kate told People in 2019 before her daughters left home. “Mady and Cara really steered the ship in terms of applying to colleges; they knew what they wanted, and I trusted them. That same feeling is going to have to carry me through my fears now when I think about them going off on their own, fending for themselves, being alone for the first time.” RELATED: See the Kids From Jurassic Park Almost 30 Years Later.
