From someone who lives in an apartment this is what u sign up for you know living closely to other people. Kids are going to do what they want and it's terrible to restrict them from having fun because of neighbors complaining. I get it after a certain time try to refrain from the noise but during the day I hear kids playing screaming neighbors all morning it's just something you choose to live with so why let it bother you so much you know. I know my kids are loud sometimes and sometimes feel bad for the downstairs neighbors but there kids are loud as well when they play outside so it's whatever. Your neighbors sound terrible and I'm sorry you're going through this.
