I am VERY VERY relaxed. I am just plain worn out on fighting about such silly things, I think I also have a very different look on "major" stuff since my first daughter almost died so many times before she was 2. My 7 yr old got the new Halo for Christmas and my 4 yr old plays it with him. I dont really tell them what they can and can't watch (except porn of course!) They are allowed to wander the woods (with a friend) Sleep overs are okay as long as I know where they are. We dont really have a set bedtime, no curfew either. just a reasonable time. Most of this is how I grew up as well.
This is an example of how every kid is different. My middle child (the one who played/watched Halo and I wasn't cool with it) is very sensitive. He so wants to be involved in those kinds of things, but has nightmares. He did not enjoy the Great Movie Ride, hated EE (near tears), and begged me to leave Haunted Mansion after we were on the conveyor to board the Doom Buggies. This was in Oct. When they moved in, he would regularly tell me that his dad (he used his gang name instead of "daddy", so charming) would stab me with a knife like Michael Myers. He was 3. His first mom let them watch one of the Halloween movies! The older two had Michael Myers nightmares for over a year.
As a result, we tend to introduce stuff slowly. Even though they had some scary moments on rides, the only one with lasting "never again" affects was EE. Our 5 yr old thinks it was the best vacation ever! Just don't count the indoor rides, after the GMR, or the fact that he didn't want ANYONE to enjoy them. Barnstormer, BTMRR, Splash? All fine.
So yeah, we're strict about potential nightmare territory because cleaning up puke after a Dora cartoon featuring a witch is no fun. Staying up half the night trying to soothe the poor kid? Even less fun.
Of course, the people at school and their friends have little to no idea about their past. I guess I just thought age appropriate material would be available, because I would never assume to go beyond that with someone else's kid.
But I'm not as restrictive as some parents. DD just joined Girl Scouts and the brand new leaders were wide eyed about parents dropping kids off and leaving. I felt so guilty that I stayed. Not for DD, but for the adults! These gals couldn't conceive of anyone leaving their girls at a meeting and even talked about a buddy system for the bathroom at the leader's house. I assured her that the girls could go 5 ft and back without a buddy. Heck, Cub Scouts don't allow drop-offs here. A parent has to stay for the meeting, even though we can be more of a hindrance than a help.
