The couple shares six-year-old son Elijah. Nation regularly opens up about the criticsm she faces for her parenting choices.
"Being a parent is tough. Sometimes it's pure exhaustion and sometimes it's pure elation. I'm not sure that there is an in-between, I'm personally yet to find it," she wrote to Instagram. "As mothers/parents, we can often be too hard on ourselves. We put this unrealistic expectation of ourselves to be the 'perfect parent'. Truthfully, there is no such thing.
"We are human, we make mistakes. But mistakes should be embraced because that is how we grow. We learn from our mistakes and keep on keepin' on. I'm so self-aware and I know I am absolutely not the perfect mum, but I give it my all day in and day out and my son is loved abundantly. So, when Elijah says to me "Good night Mumma, you're the best mum ever". That's all the fortitude I need.
