I am not yet a parent, but I know it's hard! You want your child to experience things, be happy, yadda, yadda, etc, BUT you HAVE TO MAKE GOOD DECISIONS!! Not everything is an 'in the moment' thing. When I was growing up, my parents were strict! I couldn't do certain things, and it sucked! But you know what, I look back at it now (late teens to now, when I have a mature understanding) and I am so thankful and grateful I wasn't allowed to do certain things or miss out on certain experiences. Children need structure! An 11yo should NOT be going to bed at 1am to wake at 6am. Even if she does pretend to be asleep then wake back up - check in on her and tell her its unacceptable. And her attitude seems a little OTT to me, a bit forced with the American accent.. but, that's her parents to be blamed, Telling her she's a teenager so no wonder she acts like it. E2 needs some reeling in as well.. He may be on board now, but that's because he doesn't know any better! I can guantee he will look back and ask his parents WHY they allowed him to do certain things. I understand letting your kids have fun and whatever, but they're the parents and they need to do better! Parents should be setting up their kids to succeed in life.. not fail!
