Smith has a son Trey, from his first marriage to Sheree Zampino. He also has two children - Jaden and Willow - with current wife Jada Pinkett Smith, reports dailystar.co.uk.
"We don't do punishment. The way that we deal with our kids is, they are responsible for their lives. Our concept is, as young as possible, give them as much control over their lives as possible and the concept of punishment, our experience has been - it has a little too much of a negative quality," Smith was quoted as saying by metro.co.uk.
"So when they do things - and you know, Jaden, he's done things - you can do anything you want as long as you can explain to me why that was the right thing to do for your life," he added.
