She may have accidentally removed it from the console. You can simply add it back.

Follow these steps:

Add your Microsoft account on an Xbox One console

You can add your Microsoft account to any Xbox One console. Here's how:

1. Press the Xbox button to open the guide.
2. Select your gamerpic in the upper-left corner of the screen, move all the way down and select Add new.
3. Enter the email address for the Microsoft account that you want to add, and then select Enter.
   
   Important Make sure that you do not select Get a new account, unless that’s what you want to do. If you select this, you will create a brand-new Microsoft
   account.
   
   If you’ve forgotten which email address is associated with your Microsoft account, see the Lost Account Solution.
4. Enter the password for your Microsoft account that you want to add, and then select Enter.
5. Read the Microsoft Service Agreement and Privacy Statement, and then select I Accept.
6. Follow the steps to configure your Sign-In & Security preferences to add your Microsoft account to your Xbox One console.

Best,

It is possible that you're trying to login the child account using the parent device or computer. To properly isolate this issue, we'd like to ask some questions:

• Are you trying to log into the child account using the child's device or computer?
• Have you tried removing the child account from the family account and add it again?
• Have you tried logging in the child account to other computer to check if the credentials are correct?

When will Microsoft fix this? It's been going on too long now. My daughter is unable to log into her account be sugar of this closed loop bug.
