Packing- before

How little can I take for a month? the big green bag to the far left is full of baby clothes to be donated, along with a HUGE cardboard box of bigger kid's clothing and shoes that's already downstairs. Of course there's gonna be a huge carry-on of electronics too.
Omg. A day & 8 hours to go, and i gotta figure out my water purifier and mosquito netting canopy...
