1. Tent (make sure you asemble it previously so you know how to set it up and that there are no missing pieces, since i asume you don't own one
2. Sleeping bags
3. Water
4. Food you can throw into the bonfire wrapped in alluminum (potatoes, onions, mushrooms, etc). If you are only camping for one night take one of those iron grills, so you won't have to carry a stove + propane/butane and you can cook meat/sausages or some soup. Also make smores, your nice will love them.
4. MULTIPURPOSE KNIFE - can't stretch this enough.
4.1 Flint if you know how to use it, or waterproof matches.
5. Personal higene items (toilet paper and soap might be the most important).
6. Basic kitchen utensils (plate, knife/fork, mug)
7. First aid kit (alcohol, adhesive bandages, gauze, antiseptic, sterile wipes and rinse solutions. pain and anti-inflammatory medicine. hydrocortisone cream. tweezers). Trust me: it's better to have it and not need it.
8. Lamp (a miner's head lamp works best for me cause your hands are free).
Check the weather conditions of where you're going. If there's a chance of rain, take a tarp and cover your socks with plastic bags inside your shoes. If it's going to be hot and humid, expect bugs so take bug repellent
BE SAFE: Don't wander off if you don't know where you're going, and "tell a few people where you're going & when you expect to be back."
Don't get high or drunk if you're alone with your niece. Too much responsibility and you want to/have to be 100% aware.
