Communication Do's and Don'ts

Try these eight tips for navigating the murky waters of communication:

1. Do be honest. Keeping secrets does nothing but frustrate you and perplex your spouse.

2. Do bring up an issue within 24 hours, or forget it. Don't allow a problem to remain hanging.

3. Do keep to the issue. If you start discussing who should
babysit and end up arguing over discipline, you've moved off-track.
Take a break and return to the issue when you're both rational and calm.

4. Don't criticize. You can complain—offer something specific to
the situation. But criticism can involve blame and counterattacks and
is sure to put your spouse on the defensive.
