In a co-parenting situation, I find it inappropriate to contradict the other parent unless the child's safety or well being is at stake. I certainly don't stand for it when mom tries to pull it with me. And, like I said, the fb issue ( properly managed/monitored ) itself is hardly worth the ruckus that would be caused if I reported the page.Okay...so tell mom that if she doesn't share the log in information, you'll have the page closed due to the TOS.
I think you should close it anyway. You are teaching your kid that it is okay to break some rules when they aren't that big of a deal. Where do you draw the line?
I do have concern for my daughter's well being, for exactly the reasons you specified Blue Meanie. Which is why I want that auth information. I may take Nevergrowup's advice and report the page if I'm not given authentication information.
