Doctors believe the obese baby may be suffering from Prader-Willi Syndrome, a genetic condition that leads to the hard combination of insatiable appetite and weak muscle tone.
She also revealed the family take it in turns to push the boy to a local hospital where doctors are baffled by his condition.
Ten-month-old Luis Gonzales and his mother Isabel Pantoja, 24, are pictured at their home in Mexico. By ten months, he had reached 62 pounds, baffling doctors. She wasn't anxious about her son's sudden weight gain at first, but he is now bigger and heavier than his brother Mario, who is three years old, The New York Post reports.
Lius' family is now facing several difficulties raising the child as the doctors have considered giving him hormonal treatment, which include injections that cost $555 per shot, despite his father earning just $200 per month, Daily Mail reported.
"After only one month we noticed that clothes did not fit him and we had to dress him in clothes for a 1-year-old, and even a 2-year-old", Isabel Pantoja, the baby's mother, told Metro.co.uk. Over the next eight months he gained a staggering 18 kilos.
His parents have since created a Facebook page and opened a bank account for people to donate money for Luis Manuel's medical care.
Family members take turns pushing the boy to his hospital appointments four times a week in a battered push-chair.
At the moment, despite being alert and responsive - as full of giggles and gurgles as any baby - Luis Manuel can neither walk nor crawl.
Pantoja said he is becoming exhausted from carrying him so much, despite being a well-built man who works at a juice plant.
Mario Gonzales lifts his ten-month-old baby Luis at their home in Tecoman, Colima state, Mexico on November 8, 2017.
Then recently, they were contacted by a surgeon, Silvia Orozco, who specialises in nutrition.
She concluded that his life might be in danger, but is awaiting the results of tissue sample analyses in the United States.
A number of doctors believe Luis may be suffering from Prader-Willi syndrome, a complex genetic disorder that is caused by the loss of function of specific genes.
Though she is waiting for test results to confirm her diagnosis, Orozco believes that Pantoja's pregnancy diet might be to blame for her son's unexplained weight gain.
