As far as actual discipline goes, there ARE no 'threats'. EVER. We have rules with consequences if they're broken.
My 'threats' are only ever ridiculous. Since my kids were tiny I have never once made them believe that I was really going to do something, when I didn't have any intention of following through with it.
On the other hand... I love threatening them with crazy, mean, punitive, disrespectful things.... I guess I'm just that special kind of twisted. I've threatened to chop fingers off if they touched my cake, threatened to beat them with sticks, club them like baby harp seals... terrible terrible things! I have wondered sometimes what I must sound like to someone outside my family or friends when they hear me say something like "stop making that sound or I'll duct tape your mouth shut forever" or "If you keep whacking that toy on the stairs I'm going to break it in to 15 thousand pieces". lol
I agree with the above poster who said that if your kids are sensitive, not to joke with them like that. Since my children have never been disciplined with violence, are amazingly secure, GOOD kids.... I can totally get away with threatening to beat them with sticks, and they just roll thier eyes.
I also tell them things like 'you are the most amazing person that I know, and I can't BELIEVE how lucky I am that I get to be your mom." hopefully it cancels out the threat to set their room on fire, eh?
NewChick... teenagers are so fun! One of the best ways we have of clearing a room is DH will announce "Mom and I are going to start making out!!" Poof!! all three kids are GONE. It's horrifying for them to even consider their parents gettin it on!
