In the last 10 years I've packed a lot of lunches. A LOT of lunches. I take it a bit seriously and always try to keep them interesting. They must include the basic food groups. They can't include anything orange (the it-o family-Fritos, Doritos) or soda but there can always be a sweet (but not of the fruit snack variety).
When the kids reach middle school, they take over the making of their lunches and they must follow the lunch box rules. I still cut-up veggies, bake cookies and make egg salad and the like but they have to assemble and pack. It's an easy step toward greater responsibility needed in middle school. I think it reinforces learning to feed oneself, too. Also, I am sooooo tired of packing lunches.
Occasionally, if I was feeling especially proud of the stock in the lunch kitchen I'd stick a post-it (or recycled envelope) on the inside of the "lunch cabinet". Not being a morning person, Ella was always appreciative since it takes a lot of thought out of lunch packing.
I made the dry erase frame (from Make and Takes via Pinterest) to hang on my fridge as a menu board/grocery list and I love it. One day I thought "why not hang one inside the lunch cabinet?" Duh.
3-M velcro tabs affix it to the door. A dry erase maker hung from cook's twine might be handy to prevent its disappearance.
Ella loves it.
And I love that because it's one more lunch I don't have to pack.
