Letting kids become super obese is bad parenting.
Its too easy today for parents who who can't be bothered or are maybe busy with jobs to just sit the kids in front of the TV with a bag of goodies as entertainment.
Plus all the gadgets around make it less intresting for kids to go out or participate in sport etc.
Fat kids grow into fat adults and then sucumb to all the overweight illnesses such as diabetes etc which take time and money to treat, money which could be better spent on things not self inflicted.
