At your age, we just hired a large truck. DP & I both had the correct licence to drive the BIG vans/trucks/lorries. We were forever helping friends move due to being able to do this. So when we moved we had help to load the vehicles. Amongst our group of friends, certain friends would always opt to stay home & have all the 'helpers' kids over to play. Personally I'd suggest letting toddlers/young children put some of their things in a box and into a van/car and take it out at the other house & have a grandparent/friend/whoever they love/trust play with them for a bit, maybe go out into the garden with a ball, have drink & biscuit (other snack are available). I think it helps them accept the move (as well as putting familiar duvet cover on their bed etc). I think although it's easier having grandparents take them off for a few days, it's better to have them around the move.
Then I moved overseas.. & life was very different.
so it can very much depend on your situation Even as far as vans going back & forth. If you have plenty of hand to help with loading & unloading, the vans can move very quickly. Obviously this works better if you're 2 streets away not two hours away!!
in YOUR situation I would start with another round of decluttering. Last time you were just concentrating on doing it for photos. This time focus entirely what you need/want in your new house. Do you really want x in your lovely new house? If not, donate.. Do you really need 3 of xyz? If not donate!
you don't want to be taking stuff to 'think about' later, or at least as little as possible.
ask yourself how often you've used xyz since you decluttered for photos. A lot of stuff we keep is aspirational, be realistic about whether you'll actually use the item and also consider the cost of replacing v the cost/hassle of moving & storing the items. Donate now, replace if you need it can be a great way of minimising clutter.
Dana K White I think is great. Her you tube videos really make sense and help you think about 'stuff' differently. Even sentimental stuff.
once you've decluttered well, packing really shouldn't be a problem. But start soon. There's VERY little in our homes that we need day to day!
label boxes well. Coloured stickers are great for people helping you, but also write more detail on the box. No one regrets writing more!!
pets- totally depends on what pets you have. I think you said 'outdoor' (can't scroll back to check) but if my recall is right I'd hope that one of your friends/family can help you out with moving cages/runs etc. & either have the pets in your car in carriers or board them for a few nights if family/friends can't help.
judt remember it's only 24/48 hours of mayhem & high emotions! Once you're in, you're in!
BEDS - as others have said, get them made up at the new house as soon as possible. Just knowing it's there, waiting for you, is SO nice!
TLDR: start now, declutter again!! You can do it with friends & family with vans!
