I've been making my lunch and the kiddos for a couple years now. It's more cost effective than eating out or school lunch, and I can make sure the kiddo gets what he will eat. For me, I don't drive myself to work so there isn't really anywhere to go for lunch as we don't have a cafeteria. So homemade lunch it is!
I use leftovers for lunch typically, so it's more cost effective for me. Last year, the kiddo's teacher always gushed about how his lunches were so cool and different. I thought, seriously? It's a pork chop and corn. No one else brings that? Although he has had inventive things a couple times - Po Boy sandwich with shrimp, meatball sandwich, and Indian, yum!
Lunch from home comes with a certain amount of stuff, namely lunch bags. We each have one that we use on a regular basis. Then I have an extra one I got from my rideshare company for free, a bag with a built in freezer pack, and another one for the kiddo. It's all so unorganized.
