I'v moved 30 times as an adult and what I do is:
Put boxes in each room, have an open one in every room and as soon as it is full, put another one in.
Mix heavy suff with clothes to lighten the load, and write the name of the room on each box.
I wrap up delicate things in towels, tea towels, etc.
Use up as much frozen and fridge food as you can, and on the morning of the move, strip all beds and empty all fridges and freezers, and fill them with the stripped bedding to soak up any remaining water or ice. These can go straight into the wash at the next place.
So some every day. Pack all clothes you won't use leaving just the ones you will need between then and moving.
Empty whole cupboards out, and decide to ditch, freecycle or pack. No dithering.
Buy a few large green gardening bags which will house all the 'last 2 days and first 2 days of moving' stuff, so clothes, toiletries, shoes etc and have one of those in each room to shove things in as you clear each room.
As you pack each box, if movers are moving you, stack each box in the corner of the room and put the next boxes on top. But if you are moving yourselves, move all boxes to the easiest area to load from on the day. Usually the room closest to the front or back doors. Move as you go so you don't end up exhausting yourself the day before you move.
Kitchen equipment, use clean, clothes, tea towels, bedding etc to wrap up crockery and any breakables in. Keep kettle, cups and tea/coffe and milk and take with you. Plus some snacks, you will need them as you go.
Keep back a bucket, mop, hoover, spray and plenty of cloths to clean as you leave, and take those in the car with you - you will need them the other end to clean [especially] the kitchen and bathroom as you get there.
I make up 10 boxes at a time and disribute them, get those packed and then make up the next 10. If you pack one box per day per room, it can keep you focused and on track.
