To keep us on time we pack everything the night before. Clothes are laid out and shoes always by the door. My other secret to success is my magic van. The magic van always has disposable plates, cups and silverware, a Rubbermaid container of snacks and juice boxes, seasonally appropriate change of clothes for each child as well as a set of inexpensive shoes, hair brush, nail clippers, hair ties, and when we have foster babies there are clean sippy cups, extra wipes and diapers. If a kid spills something on the way out the door, they can change in the van while the other kids are getting strapped into car seats. The "I need a drink or snack because without it I will die" is covered. Its in the van, get in your car seat and you can have it. If we use anything out of the van, then it is replaces as soon as we get home. Replacing our supplies is the first priority when we return from anywhere.
