I am assuming this is rec ball, right? If your kids play competitive soccer then they are at the age where you stop bring snacks.
Also, how many games a week do these kids have? Just one? If so wth really cares what they have afterwards. They just burned a ton of calories off. If you are doing your job the other 23 hours that day and 6 more days a week, then a little sugar snack to share with their friends after a game isn't going to hurt them.
