On move in day set up the beds first and make them up as soon as possible, that way when you are ready to collapse, you can go straight to bed
pack a small suitcase with everything you would take if going away for 2 nights and keep it in your car during the move
if you can, plan the actual move over 2 or 3 days, so day 1, pack up house and put it all in a moving lorry. Sell the house that afternoon. Day 2 buy the new hoise amd get the keys, book cleaners etc for that afternoon. Day 3 move your stuff into the new house. It needs you to be able to afford the storage cost of your things for 2 days amd an airbnb or hotel, but it de stresses it all massively.
start packing now and declutter amd sort as you go. Start with things like Xmas dec and summer gear. If you pack a box of fragile stuff, put a strip of hot pink duck tape on the outside of the box sp the movers can tell its fragile at a glance. The most important thing to write on the box is the room you want it in, in the new house.
dont pack heavy stuff in big boxes, you want lots and lots of small boxes for things like books and crockery
on move in day, set up a chair by the front door and use masking tape to put a big sign on the door of each room with its ‘name’ eg dining room, baby room, main bedroom. And then you and the baby sit in the chair and as the movers carry each box in, tell them which room to pit it in. If you have a garage or a shed, try and send the majority of boxes with non essentials to there and the bare minimum to the rooms. This will give you space to move amd then you can pull out a few boxes at a time to unpack
make sure you have all the utilities switched into your name on move in day (dont forget internet)
start packing early, it takes way longer than you think, especially if you have a baby
