https://www.internetmatters.org/ have provided some handy tips on helping to make your child’s device as safe as possible 

Set parental controls on your broadband: this helps to prevent your children seeing things they shouldn’t!

Check device settings: ensure these are set so you can only download age appropriate apps and games.

Password control: set this up or disable in-app purchasing so bills aren’t run up accidentally.

Location services: disable these so your child doesn’t unintentionally share their location with others.

Talk about staying safe: be open to talking regularly with your child about what they do online and how to stay safe.
