I'm hoping to benefit from the collective wisdom of MN's property gurus 
I last moved house 12 years ago, moving from my one-bed, single girl flat into the house that DH and I still live in now. Everything I owned fitted in the back of one self-hire Luton van, and there was only me to worry about. I wasn't bringing things like oven and washing machine with me either.
We now have three DC (8, 7 and almost-6) and a four-bed, three reception room family home packed to the rafters with stuff.
I understand all the legalities and processes involved with moving, but the prospect of how we actually pack everything up, what goes with the removal lorry and what we'd be expected to move ourselves (clothes? toys? kitchen stuff?), how we cope with three over-excited children on moving day, how long (realistically) unpacking it all is going to take at the other end.
We're only moving 3 miles away, into a new-build so no one to move out, and we're part-exing with the building company so there won't be anyone champing at the bit to move into our house.
Any tips would be very welcome!
