Definitely the parents fault:

Arya Permana from Karawang in West Java, Indonesia, weighed the same as six boys his own age and struggled to walk more than five minutes at a time. After years of over-feeding him, parents Ade and Rokayah Soemantri were eventually convinced that their young son had to have drastic surgery or he’d die. Travelling to the Omni hospital in Jakarta, Arya was the youngest person to ever undergo a five-hour gastric sleeve operation.
