David Beckham addresses Instagram posts from son Brooklyn targeting him and wife Victoria in new CNBC interview: "I have always spoken about social media and the power of social media. For the good and for the bad. The bad we've talked about with what kids can access these days, it can be dangerous. What I have found personally, especially with my kids as well, use it for the right reasons. I've been able to use my platform and my following for UNICEF. And it has been the biggest tool to make people aware of what’s going on around the world for children. I've tried to do the same with my children, to educate them. They make mistakes, but children are allowed to make mistakes. That is how they learn. That is what I try to teach my kids. You sometimes have to let them make those mistakes as well."
