Kaity Biggar revealed when her and husband Zach Shallcross' plan to start a family - even though the thought is a little nerve wracking. During an Instagram Story Q&A on Tuesday, October 7, Biggar, 30, was asked when she wanted to "start having babies" with the former Bachelor, 29. "Next fall I think???" she said. "I'm so excited to grow our family, but I'm a little nervous!" The nurse added that she still feels "like a child" herself, along with a laughing face emoji.
