I have just bought one of the compartment lunch boxes and need a lunch bag (preferably Spider-Man!) to put it in.
The way I'm doing DS1's lunch is to put little nibbly bits in cupcake cases to separate them. Storing the box on its side will mess it all up!
Do you by any chance know if lunch bags exist that carry the box upright rather than on its side? I've looked and can't find one? Should I give up or is there something out there?
