I have 2 three year olds that I bring to daycare each day. They eat breakfast in one classroom then snacks & lunch in their regular room. Their lunchbox is full with snacks & lunch and I enjoy it being separate from breakfast (they don't see what is inside and start making inane requests ).

So far, I have carried their 4 beverage cups (milk and water for each) and a plastic container of fruit and a plastic bag with a carb (waffle, belvita, bagel, ...) in a shoulder bag like this: https://www.amazon.com/gp/product/B06WWLTXFF/ I liked that it had a bit of insulation when their milk was in sippy cups - but we are upgrading to insulated cups so that is not a must have anymore.

The part I don't like about that bag is everything gets jumbled up and leaks. Then the bag stinks...even if I wash it.

I was thinking a flat bottomed bag would be perfect for fitting things in and having them stand upright. Maybe get a cheap wine bag that is 2x2 to put all their cups in within a the flat bottomed bag. (Cut the wine bag down to be a bit shorter and some how affix it to the bag?). Or I could buy 2x1 wine bags and line them up in a straight line along the bag....

Can anyone think of a better idea/modifications to my idea? Any votes on what flat bottom bag I could get?

I was looking at something like: https://www.mythirtyone.com/us/en/product/9337/small-utility-tote-green-cabana-stripe
(I have no desire for name brands or fanciness - so I'm not stuck on anything...)

The plastic containers with cut fruit are 7 x 4.5 inches. when laying flat and I don't want them on their sides.
