The disobey part is fairly simple, you win. You stay on top of them in a calm manner until they relent and do what you want. If done from the get go, they learn quickly.
If it is already an issue, then it becomes much, much harder with the crying and screaming and crap. The parent must stay calm and on point. As far as the tongue thing, that is making it known in a calm manner at the time that it is inappropriate behaves and they will be punished if they continue to do such things.
Punishments can be whatever from spanking as some do, to time outs, to taking a toy. It must be targeted at that time though and make an impact on that child at that moment. Some have their favorite blanket or toy of the day, whatever, that is what you target.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
