I’ve seen a few shows on tv about children who have some disorder where they can’t feel full. They literally crave the food - more than any normal person craves something. It is easy for all of us to say lock up the food or don’t feed him, but I think this child probably has some sort of disorder - this is horrible.
Some (including FReepers) have referred to Prader-Willi syndrome. I know almost nothing about it but obviously it’s a possibility with this kind of growth.
However, I am also swayed by those who say that China’s one-child policy leads many parents to spoil a kid rotten since it’s the only one they will have.
