メキシコで6.6kgの赤ちゃんが生まれたんだって。因みに1879年にカナダでは10.5kg､1955年にはイタリアで10.2kgという記録があり、最近では2005年にブラジルで生まれた赤ちゃんは7.5kgだったそうだ。赤ん坊がそれほどまでに大きくなってしまう原因についても元記事に記載されているのだが､専門用語の日本訳をいちいち引くのが面倒だから興味のある人は勝手にやってw

Often babies grow unusually large because the mother has poorly controlled diabetes. In these cases, too much glucose ends up in the foetus's blood. This triggers an increase in insulin production by its pancreas, which in turn prompts the developing foetus to make more fat, which is laid down mostly in the upper body.
