Likewise with tv watching-they are basically not allowed over there anyway because she is allowed unlimited and unsupervised tv watching and my kids have see very inappropriate stuff over there. We don't even have cable, just a tv and dvd player, so they feel like I"m being unfair. I don't give a crap, Family Guy is not appropriate for 9 year olds and I'm the parent in this house.
I have the same type problem. I do not have cable at my house and BF's kids do not like that. The fact that they are vocal about that causes me some distress. I also agree with you that Family Guy is for ADULTS. The mother of my BF's kids apparently let them watch whatever they want to watch, and that is just not something I have ever done with children personally (nieces, nephews, neighbor kids, other BF kids). And that is not going to change in my house.
These are your values
Transform, don't compromise. Stand strong in confidence that you are doing the right things by your kids. Trust your instincts.
I think you are doing great.
