Apple Account setup for severely disabled individual
I have a severely disabled 19 year old son who has a new iPad which is primarily intended to be used as a switch operated communication device. He is very keen to access iTunes and the AppStore so I need to setup an Apple account in his name but because his iPad is accessible to other people in his life, I also need to have control over any purchases that are made. Since my son is deemed to be an adult in law, I wonder if anyone can tell me if it is possible to setup an Apple account in his name, but as a family member, with family sharing, linked to my account?
iPad Air, iOS 8.1.2, switch operated
