For this trip, to cut down on costs, I'm packing all the clothes for my son and I in my suitcase, and in another one I'm packing all sorts of food. My son is really picky and gets upset if he can't have a pb and j sandwhich daily (or just jam when he's at school), so I'm packing a plastic squeeze bottle of jam and a small peanut butter container, bread, fruit snacks, peach and apple sauce containers, and all other goodies so we can take them into the park with us. It also means that when coming home I'll have a suitcase for all our stuff coming back!
