For those of you who have packed your kids' clothes in Ziplocs for each day, what size bags do you use? My niece is 12 and she wears a junior size 1, so her clothes are not itty-bitty. I was thinking gallon sized, but I pulled one out last night and it seemed way too tiny.

Any suggestions?

(Sidenote--Even though she is older, I am doing this with her because she is very disorganized. Her idea of "packing" is opening her closet and throwing in whatever is nearby. I don't want to spend an hour each morning with her deciding what shirt to wear with her shorts.)
