My kids are big snackers but are thin and eat well at meals so I don't worry about it. A typical dinner is a protein/starch/veg/fruit and probably dessert. My kids snack in the morning, afternoon and after dinner. It's usually cheese or peanut butter with crackers or bread, toast, fruit, nuts, popcorn, veggie sticks&hummus. I usually buy something special for the weekend like ice cream, chips or something.
