SIL keeps putting her contact details in my daughters iPad so they can message and FaceTime without my permission. I feel like it is manipulative and teaching my child to be deceitful. I have told them both it is not ok and if they want to communicate they can do so through my or my DH phone. Her iPad message and FaceTime are to communicate with her best friend only. She is only 9 and I think once you open the door she will invite others to communicate with her without my permission too. My DH thinks I’m irrational, am I?
