facetime/apple id/two ipads
2 kids each of their own ipads, but are sharing an apple id and apps. Each of them will imessage or facetime me, but i dont know how to tell which kid is contacting me. any way to differentiate the ipads using same apple id? i'd really rather not set them up another apple id with a new email account, and they also have tons of shared app stuff so it would be a headache.
