Sugar is sugar regardless of the color, brown/white, it still is sugar, don't eat to much and brush your teeth. I suppose it is true that brown sugar may have some mierals or vitamins that white sugar wouldn't as it is less processed, but I don't look at sugar as being the source of my child's vitamin and minerals, so Personally I don't think it really matters which color of sugar you give as long as it is in moderations and your child is getting vitamins from healthier sources.
