My kids are 11, 10, 8, 6, and 5, and none have it. I am not against it at all, but they don't have their own tablets or smartphones, so obviously there is no way for them to use them. If Jennah or Gavin had a way to use instagram, I'd let them. Same with FB. I know that when they do have these things, I will have their passwords and be friends with them so there won't be anything I won't be monitoring. But for the foreseeable future, that probably won't happen as my kids have no reason to have smartphones at this point
I told Jennah she can get a smartphone when she's 14, has a job, and pays her bill. Till then its just a luxury item that she doesn't need and I can't afford.
