How did I ever travel to Europe with one small suitcase for 12 weeks?

Having packed one car so full that Dan will have to squeeze himself in to drive - with no visibility, I find myself wondering what in the world I am packing to take with us for 9 weeks at summer camp. All of it is stuff that at one time or another I felt was "essential." Here is a very incomplete list (notice how much of it is for a certain 2 or 4 year old): a box of outdoor toys, kid clothes, a box of indoor toys, kid clothes, art supplies, kid clothes, tons of sunblock and toiletries, kid clothes, alarm clock with CD player, kid clothes, towels, kid clothes, sheets, kid clothes, pillows, kid clothes, blankets, kid clothes, swim suits, kid clothes, towels, kid clothes, stroller, kid clothes, clothes, kid clothes, pajamas, kid clothes, diapers, kid clothes, swim diapers, kid clothes, wipes, kid clothes, diaper bag, kid clothes, tons of snacks, sippy cups, water bottles, shoes, music, writing supplies, computers, fan, flashlights, children's books, mommy books, art books, recycle-able art supplies (baby food jars, cereal boxes and more), a coffee maker (with coffee of course), camera, and kid clothes. Have I mentioned how much clothes I need for the girls? Laundry will be done for us (I know Hallelujah), but here's the catch - about every 2 weeks! Yes I said 2 weeks. Hot summer + little divas who like to put on fashion shows + messy eaters + dirt = tons and tons of laundry! I am sure that I am overpacking - I can bet money on it, but since I don't have to pay for extra baggage this seems like the right way to go. At this point I am just hoping that when we go to leave tomorrow I have room for the kids! More to come - must return to packing!
