The 17-year-old, who is shorter than a one-year-old, will take the title by smashing five inches off the current record.
He has not grown since his first birthday, struggles to walk and cannot stand up for long, but he beams with pride when talking about his likely world record.
The current world record holder is Nepal’s Khagendra Thapa Magar, who is 26.4 inches tall.
A Guinness World Records spokesman confirmed that they would be considering Balawing’s claim.
