My kids r older but my parenting style was always different than other parents. I would often be surprised/shocked by kids' behavior that came in the door from school friends and some neighbours. Kids were crass and called the shots with their parents. On pick-up after a playdate, if the child screamed (age 5 or 6) that they didn't want to go home yet, their parents would actually come back later to keep child from screaming. A lot of the kids we didn't invite back. But they often have to work together on school projects, which is another problem, as they often don't do their part. Or go to birthday parties where kids try out foul language! Then off to teen parties. Even at a young age my kids realized the poor behavior and wouldn't ask to play again. Eventually they did find their own small group of good friends. I know a few of these older kids still and although they are actually much nicer now, they suffer from depression and some r on anti depressants.
I stayed strong with my kids and we talked about a lot (still do). I always questioned if I was keeping my kids from the real world. But I see now they're well adjusted people and have found their place with a few similar friends, and still being able to function with everyone in general.
