I would get her to help with all her toys and stuff while she is awake, tupperware, books and others things that can just basically get thrown into a box or bag, those strippy bags are really handy to move that sort of stuff with, as well as linen.

The other stuff I would do when theya re in bed at night or both down for a sleep. DD was about 10 months when we moved and that is how I did it
