How do I add a family member on to my iCloud storage?

Hey Happymanny,

That's a great question! To share your iCloud storage you'll need to set up Family Sharing and invite him to your family group. The steps under "Share iCloud+ with everyone in your family" will help get you started: Share iCloud+ with your family - Apple Support

There's also some great information found in the iCloud User Guide here: Use iCloud+ with your family - Apple Support

Thanks for using Apple Support Communities.

Take care!
