You would have to change the gamertag on the current account to something different to free up that gamertag.

Then you would need to change the gamertag on the childs account to the freed up gamertag.

Keep in mind that all this will do is change the gamertag.

If he has used that account and gamertag for games the game progress will not go over with the gamertag.

Any purchases for games or game add ons will not be transferred over.

There is a charge for changing the gamertag also if you chose that gamertag at the time of the account being opened.

Sadly there is no option available to transfer a gamertag to another account, but there is a way you can get the gamertag you want.

1. (You will have to pay if you already used the free gamertag change) Change the gamertag of the account with the old email to something else (So the gamertag can be available)

2. Use the free gamertag change on the account with the randomly generated gamertag
