If your children have an iPad or iPhone, you may want to restrict which websites they can visit. There are two options for doing this. You can set the website restrictions to only allow access to a list of preselected websites, which is ideal for very young children. For older children, you can restrict access to to adult content and designate specific websites as always allowed or or never allowed.
Go to Settings>General>Restrictions.
Tap Enable Restrictions. You will be required to set a passcode. Make sure you choose a code you will remember and that your children won't be able to figure out.
Scroll down and tap Websites.
Select Specific Websites Only if you only want to allow your children access to preselected websites. Add additional websites to the list by tapping Add a Website and typing in the complete URL.
Select Limit Adult Content if you want to prevent your child from accidentally clicking on a link leading to inappropriate content. If there is a site your child has permission to visit that the restrictions mistake for adult content, you can tap Always Allow and type in the URL. If there is a site the restrictions don't prevent your child from accessing, you can tap Never Allow and type in the URL for that site.
