Выпуск 247. Подменили? Нагуляла? Или сама родила?

A woman of 7 years is raising a daughter, although she is sure that she gave birth to a son. She was repeatedly told the sex of the child on ultrasound, and most importantly, the tags from the hospital indicated that a boy was born. The mother immediately rushed to the maternity hospital with a demand to exchange someone else's girl for her own son, but she was refused. While the blue-eyed dad and mom have a brown-eyed daughter growing up, the grandmother has found her own explanation for this. On whose side will the genetic examination be and what will it prove — substitution of a child, treason or consanguinity?
