Adults who feel the need to have children should obey the rules put forward by the council, any residents under that roof no matter what age they are need to obey it. The parents should be stopping the kid making so much noise.
Still think you should have to take a test before you can legally have kids.
The noise is from the kid running around, not screaming or shouting. Really need to start seeing the difference.
Unless you drug the kid, you ain't going to make them sleep if they're not tired. The kid could just be running round and playing in his bedroom at that time.
So, I'm assuming you haven't got kids, because you'd probably fail the test!
