Go to a room alone and scream. Most importantly, when they are ready, help them talk about their feelings. Letting children get their feelings out is like taking out a splinter before it gets infected. Teach them how to talk about their feelings without hurting or attacking other people. I feel angry when I can't go across town, because I want to be with my friends.
Children are different from each other.
Even in the same family, they may have different discipline needs. They also have different discipline needs at different ages. It's never too late. Teaching discipline is not just a one-time thing. It may be harder at first if you start when children are older, but you can do it.
