Leaving the Chucks at home

I should be packing right now. Tomorrow we will travel across the country for a family reunion and a week of fun with relatives. For this trip, for the first time since I packed for my 6-month study abroad adventure in 2003, I made a packing list. Normally I am disdainful of such crutches, which lead to things like always having enough socks and contact solution. Who needs that kind of predictability? But it is a different story to be planning a week away from home with a 5-month-old. Sweet pea doesn't need much, right? No toothbrush or toothpaste, no underwear or bras, and she doesn't even need any snacks yet. BUT she does need enough diapers and enough wet bags and enough outfit changes for multiple spit-up events. She needs a car seat and a carrier (we use the ERGO), and maybe a stroller. She needs her birth certificate because it is her only form of ID so far. I'm just not sure I can handle keeping everything in my head that I'm going to need (including the items that are new for me, like nursing tanks, nursing pads, and possibly a nursing cover) and still bring everything she needs. I do not want to come up short, so I am getting organized. Welcome to parenthood? We are trying to pack as light as possible so we have fewer bags to check, so less expense, so I will be leaving behind items such as a variety of shoes to go with different outfits, (for me and her). I know she doesn't need them yet, but aren't these shoes cute on her?
