A1. Get enough sleep.  When you feel like a human, you can handle things.

     A2. Exercise.  You will have more energy and endorphins, and daily challenges will not seem so overwhelming. 

     A3. Sometimes it just takes some practice.  Remind yourself that your children are still learning and growing (just as you are), and you have the choice of whether or not you will raise your voice, let little things bother you, or let another person's actions "ruffle your feathers."  If you do lose your patience, start trying again immediately.  You are only human--don't be too hard on yourself (or on your children).
