How can I change my child age I put wrong year and she is dropping me crazy

Hi imelda215,

If you accidentally added the wrong date on her Apple ID please follow the steps below to help you sort out your problem:

1. Open Settings App.
2. At the top of the Settings app, her name will be displayed. Tap on it and open the next section.
3. Within the next section, tap on the "Name, Phone Numbers, Email" bar and move to the next section.
4. Within the section, just scroll down and you will find the "Date of birth" tab.
5. Change the date of birth and tap on "Done" to save your change.

Stay safe.
