I have read the pasta jar and associated 'methods'.
I think I am fairly oudated in my ideas of discipline - I have always given three-strikes-and-out, on the third counting to three and then PUNISHMENT
When young this meant I would place them firmly on the floor and say NO
When older it would mean place them in their room
I've only done this a handful of times, the both respond to NO now with terrified obedience
So - what works for you, and why? And why have you chosen the method you have?
