DHAKA: Kyairiel Mikhail is just 13 months old but is already heavier than his three-year-old sister and five-year-old brother.

He was born 2.7kg, within the normal range.

Now, the one-year-old weighs 17.6kg, after losing 0.5kg in the past few weeks.

‘Doctors have carried out a series of tests on him but they, too, are baffled by his condition,’ said his worried father Khairul Syafiq, 27, reports The Straits Times.
