1. Be a team player - Regardless of who is hosting, remember to ask questions, compliment your mother-in-law or daughter-in-law, offer help and let her know you're interested in her thoughts.
2. Don't take things personally - Everyone is stressed during the holidays, so as long as you know you're on your best behavior, you can be certain "it's not all about you."
3. Find the humor - No matter what happens, look at the humor in it and tuck it away for a story about what she did "this" time.
4. Find some down-time for yourself - Just a few minutes to reflect and re-energize can be just what you need to get your energy back.
5. Establish ground rules in advance - Talk to your spouse and agree on how long you'll be staying. If necessary, take two cars and don't forget to let your family know what time you plan to leave.
And it the end, remember this too shall pass. "It's just one day," Dr. Brann said. "Anyone can get through one day."
