Cant change my childs info on microsoft account

Hello, EdiComici. Thanks for reaching out. I'm Lucas, an Independent Advisor and Microsoft user. I don't work for Microsoft.

To change a child account privacy settings, you'll need to login to the parent account at https://account.microsoft.com

Select Manage my child's profile info.

For the child’s account that you want to change, select Edit this child's personal info and then follow the instructions.

If this still can't help you, just let me know.

So try this way, not by Xbox but accessing
Microsoft Family by browser. Just log in with your account, Select Manage my child's profile info. For the child’s account that you want to change, select Edit this child's personal info and then follow the instructions. See if now you will be able to change
his name.

Usually in Xbox you cannot change your name, even you with the main account, this stuff needs to be changed directly in the Manage Microsoft Account through the website.

For most people, in most regions

Sign in to Your info on the Microsoft account website.Select Edit your personal info.Change your birthdate, and select Save.
For child accounts, in some regions
If the birthdate on a Microsoft account says that it belongs to a child, there are different steps to take in regions such as the United States of America and the Republic of Korea, and other regions that regulate what children can do online.
I'm a parent, trying to change my child's birthdate

Using the parent's Microsoft account, sign in to your Family page on the Microsoft account website.Select Manage my child's profile info.For the child’s account that you want to change, select Edit this child's personal info and then follow the instructions.
I’m an adult, but my account thinks I’m a child
To change your own account from a child account to a full account, you need to prove that you're an adult. You have two options:

Show all
Option 1: Provide a valid U.S. credit card number
Option 2: Send us proof of age

Might I be able to change it a different way

Hello, Amanda_288. Thanks for reaching out! My name is Lucas. I'm an Independent Advisor and a Microsoft user just like you. I'll be happy to assist you today.

Please try to change it using your parent account:

- Using your Microsoft account, sign in to the Microsoft Family page (http://family.microsoft.com/).

- Select Manage my child's profile info.

- Select Edit this child's personal info and then follow the instructions.

Just keep in mind changing the Microsoft child account birthdate does not change the Xbox profile birthdate of the child.

Feel free to ask back any questions and please let me know how it goes.

There is no adult account for my child account so I cant change my child account setting. I want to purchase something but cant since i cant find my adult account. When i press on family, it only comes up with my child account.
