Emotional regulation is hard enough to get a grasp of for ourselves. Teaching it to our children can be that much easier if we simply display that we are in control of our emotions. On the same note, keep the lines of communication open with your children. Let them know that ANY emotion they feel is OK. How often have you said something like, "That shouldn't make you sad." or "You can't be mad over that." All this does is tell them that what they are feeling is wrong. Instead, ask them why and offer solutions. As adults, we know how it feels to be sad, angry, mad, etc. We also aren't very happy when someone tries to tell us not to be. Accept that your kids have emotions just like you do, and they are learning to control them, just as you are. Be the example that shows them a positive way to do that.
