My girls are 17 and 18 and fight every time I go to work. My job is a 48 hour shift once a week. Their dad refuses to help at all. I had my oldest put me on speakerphone and I told them both to knock it off, stay away from each other and go to bed. I am thinking that I may need to hire a babysitter to have an adult presence in the house when I am gone. This is ridiculous and should not even be an issue but obviously it is. I don't know what else to do. I have no family or friends (outside of coworkers). Any ideas?
