Although crying is okay, it isn't always the best coping strategy. If the children see tears running down your cheeks, give them a brief explanation of why you are crying and reassure them that you're okay. While it's important for children to learn that it's okay to cry, seeing an adult cry intensely for a long period of time can be difficult for children to understand, and may even scare younger children. This is natural, and gives us time to think and recover. But it's important not to isolate ourselves or clam up for very long periods, and make sure your children know why you're being quiet or want to be alone for a little while.
Children assume that adult behavior is correct behavior.
If parents teach children, by example, how to effectively deal with anger, then children will likely use these same methods in their adult lives. This is a powerful pay-off.
