Q: How to use Apple-id

Hi there,

I am quite new to iPads and iPod touchs and all apple products. When I bought my first iPad I created an apple-id for me.

Later on my son got an iPod touch and my daughter another iPad. At that time I connected them both to my apple id and my e-mail address.

Now they want to use FaceTime, but of course they want their own facetime, Today when someones friend is calling, it is calling on all units, of course because they are all connected to my apple-id and my e-mail address. Is there any way around this?

My daugther doesn't want her "calls" to go to her brother and so on.

I would so much appreciate your answer on this issue.

Best regards

Annika
