I know we live in the technology age it's not like before, kids this days are smart with things, i won't say it's bad to allow them to have access to internet, you should allow them but put parental controls on it to allow them not to go extra miles, like there is a video that went viral it's about a 10 ages old girl with TikTok account that she post her sexy dance video that got many shock. It's better for you to expose them to some certain things, one thing you should know is that if you restrict your child too much at home when she goes out other kids will expose them to those things and it might be in the wrong ways. Internet have really corrupt so many kids, they was another video that a lady was crying because of her kid sister, she didn't know that her sister was busy watching s$x video, because the child is always deleting it after watching, the lady wake up one morning and decided to check her delete files on iphone she was shock to see what her sister was watching. One thing you should know is that the internet can make people or break people, it's just the two way round, give them that freedom but not too free. It doesn't matter the age because age it's just a number, there are.
