"That and he doesn't feel like he needs his medication... But Kyle and I have a very good, fine relationship. But Kyle is bipolar. So when you have a child that deals with that, today I'm your best friend. Tomorrow you don't know who I am. As a family it's our job to continue to love him and pull through."

As far as whether fans will see Kyle on the show again, Todd said that there is hope.

"When he gets his stuff together. If you can't be courteous and polite you can't play. [But] Kyle is my son. He is welcome in our family at all times."

Kyle told a very different perspective to the situation Oct. 24. In an interview he said that Todd was a "snake" and kicked him off the show after he took custody of his two-year-old daughter Chloe. He said his father is using Chloe for better ratings.

"This show has been nothing but bad for me. At this point he's ruined me and he's ruined the other three kids he's had who are spoiled."
