If you will be cooking at your tent (as opposed to going out to places for food), make a Kitchen Box. Big tub with a lid with all the cooking items which can be left outside the tent. In it:-
Camping stove (plus extra gas)
Plastic plates and bowls
4x cutlery
Saucepan and frying pan
Washing up bowl
Spatula and tongs
Mugs
We keep small Tupperware tubs of coffee and teabags in our kitchen box, plus a small bottle of dish soap, a lighter, a sponge for dishes, a tea towel, and a couple of carrier bags to use as a bin.
We take camping chairs and a folding table (highly recommend visiting Decathlon for these).
Inside the tent - something to sleep on (SIM or air bed or camp bed). Pillows (take from home, the inflatable ones are shite). We use duvets as I hate sleeping bags. Worth chucking an empty hot water bottle in to fill at bedtime if cold. We use a large blue IKEA bag for our clothing. We all wear Crocs the whole time as if it rains you wont get trainers wet (wellies would do). Torch (x2) for inside tent after dark/walking to loo.
Zippy freezer bag for milk/meats etc.
Packets of dry pasta and a few jar sauces for dinner, some barbeque foods if theres permission for a fire.
What are you doing for the 1yo bed? Do you have room for a travel cot?
