Lindsay Arnold Shares Video of Daughter Sage, 14 Months, Mastering Swim Lessons: 'So Proud' Lindsay shared the news of Jensen's arrival on Instagram last week following Jensen's own announcement. "So in love with this perfect boy and so proud of his parents," the dancer wrote, tagging Jensen and her husband, Topher Hill, and adding a red heart emoji. "HE'S HERE." Lindsay welcomed daughter Sage Jill with husband Samuel Lightner Cusick in November 2020. Last year, Arnold spoke to PEOPLE about the pressures of being a mom and how she reminds herself that no parent is perfect. Lindsay Arnold Cusick/Instagram "I try to focus on the fact that there must be so many moms out there that are feeling these same pressures," she said. "And if I can be open and vulnerable about it, maybe I can help other moms who are feeling the same way, and understand that it's okay and that none of us are perfect. There are trials when you're a mother." Arnold continued, "There's things that you're still learning and trying to grow every single day and you're not alone. That's kind of what drives me. And at the end of the day, I try to focus and remember that I know what's best for me and my family."
