Sounds like a fine technique to me, I don't have kids so I definitely cannot say what is right or wrong and obviously there probably is no right or wrong when it comes to parenting as long as you aren't doing nothing when your kid is acting up. My grandparents used to take their kid to the car if they were doing something wrong in the store, of course there were 2 parents so this meant one would sit in the car with the bad kid while the other finished the shopping. If you got taken to the car then you got punished when you got home and it believe me you were in for it thus the misbehavior probably didn't happen again. It's funny I hear stories about my parents but that describes about one tantrum per year, now it seems like kids have one full out tantrum per day or week, what is going on here?
