Mom with Lou Gehrig's disease gives birth to son

The baby boy weighs 2.9 kilograms and is healthy. He will undergo further genetic testing to determine if he has inherited the disease from his mother.

The baby was named Miduo, literally meaning "an abundance of millet". "They hope the boy could earn himself a living in the future," said Tian's mother-in-law.

The couple lead a hard life, as Tian helps process photos for others and her husband is a blind masseur.
