Although Babatunde Fashola, affectionately known as Baba, is 22 years old, he is less than 70cm (2ft 4in) tall.
He has cerebral palsy and requires lifelong care. He can neither speak nor walk and is fed via a tube attached to his stomach.
As a baby, he was abandoned by his parents but 10 years ago, he found a home at the Cerebral Palsy Centre in the Nigerian city of Lagos.
“Baba weighs about 12kg [26lb]. He is doing well,” the facility’s founder, Nonye Nweke, tells me when I visit.
Ms Nweke and her staff work around the clock to support him and other youngsters living with permanent brain damage.
Although there is a lack of official data, cerebral palsy is believed to be one of the most common neurological disorders in Nigeria. In 2017, a medical professor from the University of Lagos said 700,000 people had the condition.
For many of those living with cerebral palsy in the country, their condition was caused by a common phenomenon among newborns – neonatal jaundice.
