Выпуск 925. Родила сына, а отдали дочь?

47 years ago, his wife gave him a daughter. True, my beloved assured me that she had given birth to a son, and on the baby's tag it was written "boy". And recently a man found out that 47 years ago he became the father of both a girl and a boy, because his wife gave birth to twins. Was his own son really given to another woman who gave birth on the same day, but lost the child?
