... what tools do you find helpful? What kind of lunch box, cold packs, food dividers/bento boxes, fun shapes, etc do you use for you LOs lunch?

I'm trying to make a list of things I'd like to get the kids in the coming months if I see items go on sale. DS is 2 and doesn't have a backpack. Neither does DD but it seems less of a thing with a 1 year old. But I see all the cute bento lunches and I wish I could make something look that good!

So what are your go to favorites?
