Amy Roloff was more than happy to have her grandkids as part of her big day.

On Saturday, the 56-year-old Little People, Big World star married Chris Marek at Roloff Farms in Hillsboro, Oregon. Serving as her ring bearer and flower girl were her grandchildren Jackson, 4, (son of Zach and Tori Roloff) and Ember Jean, 3½ (daughter of Jeremy and Audrey Roloff).

Amy shares four children with ex Matt: twin brothers Jeremy and Zach, 31, daughter Molly, 27, and youngest son Jacob, 24, all of whom helped with the special day.

"They all have been wonderful," Amy told PEOPLE. "They've been helping me all this week with setting up and, most importantly, moral support. Having my grandkids be a part of our wedding day is so special to me. To know that they are happy for me means so much to me."
