Top idea hun.

This is my fourth move in four years. If you have ten minutes when she's occupied have some boxes ready to go in the garage and pack non fiddly stuff. Only really takes ten minutes to fill a box and if you do that a few times a day it goes pretty quick.
Save the kitchen/buffet breakable stuff for Wednesday.
Pack a box specifically to open when you get their. One for you and DH and one for the girls. Essentials - toilet paper, kettle and cups/spoons/coffee etc, toiletries, toys, change of clothes, snacks etc.
