Say you were a guardian or parent and get to decide when a child can get a phone or use a computer and get internet with it. If you wish you can also install software and change router settings to what you see fit.
Some parents decide to forbid the internet completely, others are more relaxed. Some go the helicopter route, and some do not care whatsoever what their kid does online.
What is your policy on letting a child use the internet?
Only with my eyeballs in presence. My son is autistic and barely verbal. He also has combination ADHD. I wish I could forbid the tablet entirely but it just doesn’t work with a child facing these challenges. For example, he can’t sit still through dinner so if we go out, he uses tablet until the food comes. He’s obsessed with Legos. All the content he watches is Lego builds. He watches that on YouTube kids with me present to make sure he doesn’t slip through the cracks. My eldest is 19 now and we let him access the internet unabated, that was a huge mistake I highly recommend people know exactly what their kids are watching and you should restrict traffic to safe content only.
