Birthday

We have similar birthdays! My birthday is today (feb 15)! Hope you had a wonderful birthday and a Happy belated birthday as well!

They don't let the account holders change their DOBs as this would allow the children to change their DOB on their account and subvert any age restrictions their parents may have set up with Parental Controls.

In normal life, you tend not to change your DOB.

you can sign in here https://account.microsoft.com/ using your daughter's account

once signed in go to "Your info" and then "edit personal info" change the DOB there.

Nope...her birthday is set in stone. Is that something that Xbox can change if I call them?

Hi,

you can sign in here https://account.microsoft.com/ using your daughter's account

once signed in go to "Your info" and then "edit personal info" change the DOB there.

there is no way at the moment to transfer Gamerscore to other accounts, you can share gold by setting the xbox one she uses to "my home xbox"

how to setup "my home xbox" is here
support.xbox.com/.../my-home-xbox

Xbox live accounts cannot be deleted from Xbox live altogether just from the system, if a new gamertag is created your daughter will need to have a new gamertag, if you want to use the current gamertag you will need to change that one and that will cost
you money.

Happy Gaming!
