I downloaded a new app from the Amazon Appstore. How do I make it available in my child's profile?
By default, apps you download from the Amazon Appstore are not automatically accessible to your child. Follow the instructions in this tutorial if you wish to make them accessible from your child's Home Screen.

First, swipe to the second page of your child's Home screen, then touch the Parents icon to enter Parent Settings.
Screen: Original Kidibuzz? System Home

Touch the App Settings icon.
Screen: App Settings

You'll see two tabs within App Settings. The VTech games that came with your KidiBuzz™ 3 plus any games you've downloaded from Learning Lodge® are all listed under the "VTech Apps" tab. Any content you've downloaded from the Amazon Appstore will be listed under the "Other Apps" tab.
Screen: App Settings > VTech Apps

Touch the "Other Apps" tab. Then touch the check box next to any apps you want to give your child permission to access.
Screen: App Settings > Other Apps

To access an app from the Amazon Appstore from your child's profile, select "More Apps" from the child's Home screen. Then, select the app on the next screen.
Select 'More Apps' from the child's Home screen

If you change your mind and want to remove access to an app later on, just repeat the steps above to go back into App Settings and uncheck the box next to the app you wish to restrict.
