Hi all

My daughter starts kindergarten next week and I’ve pretty much have figured out everything except for the lunch box. She’s an only child(so I don’t have much experience, learning as we go), super picky eater and I don’t expect her to eat lunch prepared by the school. I want a lunch box that will keep food cold or hot depending on the meal. I’ve been looking into bentgo lunch boxes but they’re a bit expensive. What would you all suggest as a good lunch box?
