The biggest risks on Instagram for a 14-year-old are exposure to strangers (predators, catfishing), cyberbullying, addictive scrolling and unfiltered content that can hurt self-esteem. To keep her safe:
- Set her account to Private so only approved followers see her posts.
- Turn off location sharing in her profile and posts.
- Use iOS Screen Time (via Family Sharing) to impose daily app limits and downtime.
- Enable two-factor authentication on her Apple ID and Instagram for extra security.
- Have regular check-ins—go over her followers, review DMs together, and encourage open chats about anything unsettling.
On iPhone you get rock-solid privacy, prompt security patches and built-in Family Sharing controls that make this way easier to manage. Android can feel a bit fragmented—updates are slower and there’s a higher chance of rogue apps.
