After overcoming a rare type of cancer, The Little Couple star Dr. Jennifer Arnold says she made some big changes in her life.

“You look at things differently,” she tells PEOPLE.

Arnold, who works as a neonatologist at Texas Children’s Hospital in Houston, recently decided to scale back her workload so she could spend more time with her husband, Bill Klein and their children – 3-year-old daughter Zoey, whom they adopted from India in 2013, and son Will, 5, whom they adopted from China earlier the same year.

“It’s this work-life balance that’s very hard for anyone, and I think having gone through what I’ve gone through has made me re-evaluate,” she says. “I just took a big step down from clinical and am no longer seeing patients.”

Arnold who has now been cancer-free for two years, says her physical health also played a role in her decision.

“Being a little person it’s getting harder and harder, but it’s also just trying to make sure that I have enough energy in me to enjoy being a mom and actually be there for my kids.”
