Teen, iphone, more than one guardian

Really depends on what you mean by “nested.” If he is already part of a family share, you can simply be added to that family share as an adult. If he already has purchased content, games, etc tied to his current Apple ID that would otherwise be lost, that’s the best option.

Here are the key steps to get both you and your ex set up as guardians on your son's new iPhone:

1. Create a new Apple ID for your son that is not nested under anyone else's Apple ID.

2. When setting up the new iPhone, use this new Apple ID for your son during setup.

3. Once the iPhone is set up, go to Settings > [Your Son's Name] > Family Sharing.

4. Tap "Add Family Member" and enter your Apple ID to add you as a parent/guardian.

5. Have your ex also add her Apple ID in the same Family Sharing settings.

6. Both you and your ex will now be able to enable parental controls and restrictions as desired.

7. Even though you use Android, you can manage settings and restrictions through appleid.apple.com by signing in with your Apple ID.

The key things:

- New non-nested Apple ID for your son

- Add both you and your ex's Apple IDs to Family Sharing

- Both of you enable parental controls/restrictions as desired
