How to add child to new iPad
My primary account and user is on my iPad mini. I purchased 2 ipads for my children who are under 13. So far, I created one family account for one child on my iPad mini; however, when I attempt to use her created iCloud username and password on her actual new iPad device it says it is already in use (obviously....because it is the one I created on my iPad mini for her). How do I go about setting this up?
