When kids see their parents fighting, it may have an effect on their brain development. Here are some things to keep in mind when arguing in front of children.

It's not news that kids who grow up in violent homes are more likely to become depressed, antisocial or violent themselves. But new research shows that children who are exposed to high levels of family discord or experience physical abuse share a pattern of brain reactivity similar to that of soldiers in combat. While your home may not be turbulent, even run-of-the-mill fights with your partner may be stressful for little ones to witness. When this stress is sufficiently severe, it is “likely to have a measurable effect on their brain development,” says researchers of the study from University College London.

Yikes. So should we Botox all the emotion out of our faces? Please. When your main squeeze doesn't tell you about the impromptu in-law visit, you have our permission to squabble. Just fight the right way.

LET IT OUT

Holding in your anger or disappointment for the sake of the kids isn't the best idea. “Unspoken tension can be more stressful than actual fighting,” says family counselors. “Kids will fill in the blanks of what you're not talking about and will let their imaginations run wild.” It's best to address the issues now before the silent treatment sets in.

FIGHT FAIR

Your kids will face their own share of sandbox spats and playground throw-downs, so think of your own skirmishes as teaching opportunities, says experts. Model appropriate behavior: Avoid demeaning words, express your feelings (“I feel frustrated because…”), and keep your hands to yourself.

FOLLOW UP

Arguing in front of the kids can teach them an important lesson: People can disagree and still remain connected. “Disputes don't terminate relationships,” says experts. Talk to your children about it. Tell them “Mommy and Daddy fight sometimes, but we always love each other and we'll work it out.”

MAKE NICE

If your kids saw the fight, make sure they see a reconciliation, too. And don't try forcing a superficial one for their sake. Kids will pick up on that, too.

In conclusion, counseling can also show you both how to recognize and acknowledge the parts you each play in the drama, provide a safe place to air feelings, and, most important, teach you strong communication skills. In fact, even good unions can benefit from checking in with a pro when you hit bumps, so you can get better at articulating your concerns and resolving your differences calmly when you see land mines ahead. In the end, you'll be helping both yourselves and your children.
