How to change adults email to child' email in minecraft?

Hello!

My problem is that my dad made me a minecraft account a long time ago and it is in his email. This is troublesome because everytime it logs the account out, he needs to come and put the password in. So I am asking that is it possible to change the minecraft account's email to mine so that I could get control of the account because it was meant for me and I play minecraft and my dad doesn't, plus I don't want to buy minecraft again so that I could make a account with my email and lose very much progress in the game itself and in a lot of servers.

Dear regards:

:)
