According to Hollywire, Pinkett Smith believes that 12-year-old son Jaden and 10-year-old daughter Willow are still getting a normal childhood despite their fame.
She said: "Our children are allowed to stay in the paradigm of being a child. They don't have to take care of their families: become the complete emotional, physical, and financial focus that happens to many child stars."
She continued: "This isn't about fame or money. They were still going to have their trials because of who their parents are. As much as I wish I could figure out a way I could protect my children, they have their destiny. I'm not going to put the brakes on that out of fear."
Pinkett Smith revealed last year that she uses "agreements" rather than rules to get her children to co-operate.
Willow Smith is currently in talks to play the orphan Annie in a remake of the classic film.
