Lindsay Arnold couldn't be prouder of her daughter's swimming skills.

"SO PROUD 😭😭😭 currently bawling watching this video 💕 can't believe how big my sweet little girl is getting and watching her grow and learn is truly the best thing about being her mama. We are so proud of you Sagey girl 💕 time goes way too fast 😭 #swimmingbaby #babyswim #1yearold #swimlessons," Arnold captioned the video.

Arnold welcomed her daughter 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.

"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."
