Guess I'm just contrary; we never restricted the kids cell phone use. Teenagers life revolves around the phone these days. After the Kids suffered from some of their late night antics and our laughing at them, they learned self restrain on their own. They are grown up now with good jobs and relationships, so I guess the no discipline/ no curfew with all the hunting and fishing I could throw in worked for us. I never spanked or restricted our kids--only supported them for things I agreed with and pointed out the society consequences for stupid behavior--the choice was theirs.
