Before moving or relocating, everyone should prepare an essentials box, a box full of items you'll need for your last few nights before you move and/or the first few nights in your new home. This should actually be the last box you pack before you move, but it's a good idea, while you're going through the cupboards, drawers and shelves, to identify what you'll need for the first few hours/days in your new home. This box will be the first box you open and should include items that will enable you to provide small meals, clean, deal with small emergencies and possibly entertain you while you unpack the rest of your home.
You may not be ready to pack your Essentials Box yet, but that doesn't mean you can't start making a list of items to include. The rule of thumb is to include all essentials that you'll need for at least 24 hours. Presumably, there's a grocery or convenience store nearby, but just in case, you should have some food stuff on hand that you can quickly prepare for your family. After you've prepared your Essentials Box, take it with you or make sure it is marked "Load Last/Unload First."
