In the photo, a three-year-old boy stands on a stool to help straighten up his paralysed father's head.
The boy, nicknamed Tutu, often imitates the adults caring for his father. He asks to perform tasks himself, such as feeding his father through a tube.
His dad suffered a brain injury and has not yet recovered.
"When Tutu was about to take a nap, he noticed his father's head tilted to the side, so he went over to help him adjust it," his mother explains. "But he is too young to hold it steady."
Tutu's love for his father comes from his mum teaching him that "dad is sick, so we all have to protect him."
