Rycroft, who suffered from postpartum depression after giving birth to Ava in 2011, opened up with ET in May 2014, less than a month after welcoming Beckett. The former reality star said her second pregnancy was very much the opposite.

"It was always in the back of my mind, because that was such a brutal time in my life, and I was so stubborn about it and it lasted so long, but I knew instantly when I had him, that it was a different experience," Rycroft revealed. "Emotionally, it felt so different." Check out the video below for more from the DWTS All-Stars winner, including her future dating advice for her kids.
