I always thought I'd do the curfew alarm clock thing where they have to come in and turn off the alarm when they get home so you get awakened if they don't make it. I really haven't had the need.

for everyone who complains about losing sleep when their kids are little...havent a had a teenager yet!!! 
I was 20 years old and I still had to follow my parents rules. 
Explain the curfew alarm clock thing to me. I'm assuming I set my alarm for say 11:05 if their curfew is 11. When she gets home she has to turn it off. The only thing is I have to have my alarm set for work in the morning. I'll have to look to see if there's a way to set 2 alarms. I just can't stay up that late with having to get up early the next day. That's why I was asking if everyone waits up. I was having her come down and shut my door so if I wake up and see my door shut I know she made it home. It's still scary though.
