If your child begins to act out the anger you were expressing, take a few deep breaths yourself to make sure you are feeling calm and in control, then shift yourself into low gear and move toward her. Hold your child and wait for the angry behavior to pass, which it will. Don't try to talk your child out of her anger; instead say, "I know you're upset. Mommy and Daddy aren't angry any longer. Everything is okay."
Finally, if you do lose your cool with your partner in front of your child, be sure to make your toddler (and even your baby) aware that the conflict has ended once you two have resolved the issue. Modeling peaceful, authentic resolution to fighting is the best remedy to alleviate its resulting stress.
