My DC always had a phone on the provision I could monitor it, know password at all times etc. I don’t check it often but do spot check every now and then.
Ex husband is now saying he doesn’t support and that I’m totally invading DC privacy. He has told the kids this. Says I need to trust them.
It’s not that I don’t trust them, but at 12, one of them is still a child and I feel I need to protect and educate from potential risks.
YABU - Stop checking
YANBU - Its fair to check your child’s phone
Incidentally, we more parallel parent than co-parent and have a poor relationship.
