Yeah, it would be one thing if the kid were just overweight, but that's severely obese.  That's a lot more BMI than you get just from eating Halloween candy.  I loved ice cream as a kid.  I loved that at the Gifted and Talented summer camp I went to, the college campus it was at had a cafeteria with unlimited ice cream.  Still didn't get fat.  I weighed 125 pounds in high school.
