Jana Kramerhas already learned a valuable lesson from her two young children.
“Being a mom has changed me in so many ways. I had zero patience before kids,” the country singer, 35, tells PEOPLE exclusively for this week’s issue. “I love singing, I love acting, I lovedoing my podcastand creating things, but being a mom is what truly fulfills me. It is the best part of my day, even though it’s the most stressful.”

The formerOne Tree Hillstar also credits her role as a parent for teaching her and Caussin, 31, how to communicate better.
“Our marriage, you think would be more stressful, and don’t get me wrong there are times when we are sleep deprived and short with each other because we’re so tired and you take that out on the people you love, but we have a quicker rebound now,” says the singer, who hostsWhine Down with Jana Kramerand often features her husband on the podcast.
While their kids require a lot of time, the pair are also committed to their relationship.
“We have to take care of our marriage and make sure we have intentional time, which has been really nice,” Kramer adds. “You need that in a marriage. You’ve got to make sure you have time for each other.”

In June, Kramer opened up to PEOPLE about how the couple endured three miscarriages and two chemical pregnancies before conceiving naturally following a failed IVF cycle and subsequent loss that February.
“It’s hard because it’s like, ‘Have hope,’ but when you’re in that moment, hope is the hardest to find,” she said. “It’s so hard not to [stress] when you want a family so bad.”
“We’re bringing a child into this world. We have to be there for each other and continue to do our own recovery work for him and me and be in a place where we’re bringing [our son] into the best environment possible.”
