I got tired of hearing things like "Mom, what should I eat?" and "There's nothing to eat!" (after I'd listed several possibilities). So I made the boys their own snack menu, to look through whenever they're hungry. I printed it out, laminated it, punched a few holes in it, and put it all together with pipe cleaners, which allows me to add more pages whenever I want.
There are more than 70 snacks on our menu right now, so I used dry-erase markers to show them what's available–what they can make themselves, what they'll need help with, and what they'll have to wait a little while for–and what's not available. At the end of the menu, I added a page for them to fill out with dry-erase markers anything they want that's not available–so in addition to having to read the menu, they get some writing practice as well. Now I just need to find a frog's eyeball for my future mad scientist...
You can print the snack menu here. The snack ideas on the menu are all healthy, although some of them might not sound it. You can find recipes for many of these ideas at Chocolate-Covered Katie.
