Our daughter took her lunch 90% of the time all the years she was in school. In the beginning I packed it, but once she was in about 4th grade she started making it herself.
I always included her in what was going into the box each week.
The moms are correct, some kids want the same lunch for weeks or months and all of a sudden they will change their minds.
Our daughters favorite lunches included combinations of the following.. . Plain ham sandwich on wheat bread, plain turkey sandwich on wheat. PBand J.
Pretzels with Peanut butter.
Carrots, celery, and cucumbers slices.
String cheese, Cubed cheese.
Pretzels, crackers, or baked potato chips.
Chinese pot stickers. Egg Rolls.
Lettuce wraps.
Flour tortillas with chicken fajitas.
Salads with lettuce, chopped veggies and grilled chicken pieces.
Cold slices of pizza.
Pasta with sauce on the side.
Apples, grapes, raisin boxes, dried apricots, dried apples.
I know some moms used to freeze the juice boxes and then put them in the lunch box to keep the food cool.
