watch the tv shows....the worlds strictest parents.... dealing with teens, rebellious, using drugs, out of control...they seem to have a great success rate...
for the younger children...there was a nanny show... she sent them to the naughty corner...where they had to sit...do nothing..then come out and apologize for the unacceptable behavior
sending them to their room, where they have access to all their fav things..is not advised since they may do something naughty, to escape from another event or chore...
