"No matter how busy I am... I truly always — or try to — make time for my son and daughter. I never want them to feel less important than anything else I am focused on," she said.
"Try to turn off the TV during dinner, try not to be on your phone when you're with those kids… take those five minutes after school to talk to them about their day and what they want to be when they grow up," she added.
