Collin was sent to a behavioral health institution in 2016 when he was 12, which led to the deterioration of the relationship between him and his mother. “Collin has special needs,” Kate told People in 2016. “[There’s] a fairly fluid diagnosis of what those needs are, but he needs to learn certain strategies to help him deal with things. This has been a struggle we’ve had for a very long time, and it’s one I’ve dealt with on my own. I’ve felt very alone in this. By the same token, it’s not something that has only impacted me or him—our entire family has been impacted.” Telling his own story, Collin told Entertainment Tonight, “I was in two different institutions. Scary place. I was actually 12 when I got admitted there, and then I spent my 13th and 14th birthday there.” He added that he believes that “being in a place like that does more damage than it helps you.” Collin wrote a passionate letter to his father begging him to bring him home from the institution. In 2018, Jon won sole custody of his son when Kate did not appear in court, as reported by Us Weekly. Of his mom’s rationalization for sending him away, including describing him as having “special needs,” Collin told ET, “It’s unfortunate that that’s the way my mom phrased me as a person. I don’t see those things, and I don’t think anyone else sees those things. And I hope that if we met again one day, she would understand that that’s not the case.” The high school senior also said of Kate, “My mom had her own agenda. I don’t know exactly what that was, but my agenda was to make it out on top of that tough spot.” For more celebrity news delivered right to your inbox, sign up for our daily newsletter. In addition to not having a relationship with his mom, Collin is not in touch with his siblings other than Hannah. Hannah had also decided to live with their father. “I have always been closer with my dad and we’ve always had a strong good relationship,” she told ET in May. She also explained that she is in contact with her mom and siblings, unlike Collin. “I have not spoken with my siblings in probably five or six years now. It’s tough,” Collin told ET. Collin’s other sisters and brothers are 22-year-old twins Madelyn and Cara and the remaining sextuplets, Aaden, Alexis, Joel, and Leah. Collin shared that he hopes he and his siblings can rebuild their connection someday and look past any issues they’ve had with their parents.ae0fcc31ae342fd3a1346ebb1f342fcb “I love my siblings. I would be willing to put my parents aside and I have. In my eyes, it’s me and my siblings. I love them to death,” Collin said after tearing up. “I love them very much. How I see it is, without parents involved, it’s just me and them. I really hope that one day when I have kids that my kids will know their aunt and uncles.” He went on to say that he is waiting for them to reach out first. “I want to respect their space and their time and respect how they feel about everything, so I’m kind of just waiting for the day that they reach out,” Collin explained.
