The safety of Instagram for 12-year-olds depends on how it is used. If a parent sets appropriate boundaries and monitors their child's usage, then Instagram can be a safe platform for them to use. However, if the app is not monitored or managed properly, there are potential risks such as cyberbullying, exposure to inappropriate content, and online predators that could put children in danger. It’s important for parents to educate themselves about the risks associated with social media platforms like Instagram and discuss these topics with their children before allowing them access.
