Hello zizzi b!

Thank you for posting in the Microsoft Community.

To change your child's account to an adult account, you will need to follow these steps:



Account promotion from a child account to an adult account is no longer necessary for Xbox profiles. After your account’s birth date reaches the age of majority in your region (for example, 18 in the U.S.), your account promotes itself automatically. However, if you’re in an Xbox family group, you may still observe certain content limitations.

For details about parental consent or removing yourself from an Xbox family group, please see: Why you're being asked for parental consent | Xbox Support



We're looking forward to hearing from you. If there are any inquiries about our description or if there are any misconceptions, do reply to the post.

Thank you for understanding.

Well, first of all, you should NEVER use your own account to let your kids play on the Xbox. As you see, you're locking yourself out of many options, and if you change the age for the account, your kid is regarded as an adult, and can't be restricted.

You basically have three options:

You take over the account, change the birthdate, so you're adult again, and then create a new account for your kid and add that child account in your adult family account. That way you can manage what your kid can do and see on Xbox.

Or you abandon your account, and create a new adult account, add your old account as a child account to your own adult account in the family settings, and then manage your kid that way.

Or you move your kids Gamertag to a newly created Microsoft Account email with proper age information, then change the birthdate of your own account to make yourself adult, and then manage your kid's child account through the family settings, after adding
your kid to your family settings.
