Lesson #2: Promise your group candy at the end of the field trip if they behave perfectly. They will behave like angels! (turns out the candy store was closed, but they didn't know that until AFTER the field trip was over! hee hee)
Lesson #3: repeat these words in your head about every 20 minutes: "It's only 4 hours... it's only 4 hours... it's only 4 hours". (No, you can't bring a hip flask to "help" you through this mantra, either.)
Lesson #4: some people's kids only seem like brats until you talk with them or if you are really nice to them. Other people's kids really are brats- through, and through. Those are the kids you make be in the teacher's group!
Lesson #5: IT's ok to be the "fun" mom on a field trip. IT really does make the day go better if you have fun along with the kids!
Lesson #6: Be prepared to sink into a catatonic state upon your arrival home. Be sure to have a bag of Doritos, a cold diet coke, and some chocolate within arms reach before collapsing on the bed. You won't be moving off your bed for about 2 hours. (Who knows how those teachers go a whole school year without totally losing it?!)
Lesson#7: Go on as many field trips with your kid as possible. You will be so glad you did, and more importantly you kid will. (when I walked into my son's room today all the kids perked up and said "Oooo... *bleep's* mom is coming! She comes on every field trip we have, and she's awesome!" Ya... that made my whole day right there!
