Following another thread I posted, I've decided to make DD a snack box that she can pick at through the day. I'm still going to offer meals but also let her have access to other foods as she prefers to graze. Am a bit stumped as to what to put in it though. Ideally I'd like it to have a bit of all the food groups in and would like it to not be too messy. I don't mind crumbs but don't want sloppy stuff spread everywhere. Any ideas? TIA
