edit my childs email address

Hey There 🙋🏽‍♂️

If you’d like to change the Email Address of her existing Apple ID, then simply:

1. Go to appleid.apple.com and sign in.
2. In the Sign-In and Security section, choose Apple ID.
3. Enter the email address that you want to use as your Apple ID.
4. Choose Change Apple ID.
5. If you changed your Apple ID to a third-party email address, check your email for a verification code, then enter the code. Learn what to do if you didn't get the email.
6. If you use services like iCloud or Messages to share with friends and colleagues, sign in to those services with your updated Apple ID.
