From the XBox website:


Managing Xbox LIVE Activity
Xbox LIVE Controls come into play only when you take Xbox 360 online, and they're linked to a child's profile and gamertag. When an Xbox LIVE account is created, the service asks for the member’s age to determine whether to apply Family Settings to that account.
Parents are also required to create or use an existing Windows Live ID. The Windows Live ID is associated with the child’s Xbox LIVE account and protects the settings from being changed later by the child. To change a child’s settings, first select the child’s account name and connect to Xbox LIVE. Once signed in, enter your Windows Live ID password to unlock the settings.
To see these controls, go to My Xbox, open System Settings, then selectFamily Settings, Xbox LIVE Controls.
