So I'm 27 and my 18 year old brother is asking to come and live with me (I'm in AZ and he currently lives in Alabama with my mom). I'm married with 3 kids (ds7 dd5 ds14 months). My brother is a good kid never been in any trouble or anything and DH gets a long with him well and of course the kids adore him so we are agreeing to it. He wants to finish school here. The thing is, I was the queen of sneaky and deception at 18. My mom is a pretty liberal and naive parent lol. I'm just wondering what set of rules should I have for him. I'm giving him the same curfew I had as a teenager which was home on weekdays by 9pm and 11pm on weekends. The thing is, I have no clue what punishments should be for missing curfew or any other stipulations. Help...I have no idea what I'm doing as a "parent" of an 18 year old. I thought I had a while until I needed to worry about it lol.
