How to teach children about behaving
It really starts at home. We get them to re-do things. For example if the two little boys are teasing/yelling at one another we have them re-do it by giving the item to the one who wanted it and the other to ask nicely.
We talk to them about how we expect them to behave when we go places. If we are going to the store, they are not to touch things, they are not to ask for things, if they do they don't go the next time.
Things like that.
