Bava Batra 141 - Gifts to Unborn Children

If one whose wife is pregnant says, "If my wife gives birth to a boy, he takes a hundred zuz ($5,000), and if to a girl, she takes two hundred zuz - the infants acquire the money. If she gives birth to a tumtum (a person of indeterminate gender), he does not get anything, but if he is the only child - he inherits all.

So the man prefers a daughter? But we learned that one should leave a son! Either he realizes that a daughter needs more, or he follows Rabbi Yehudah's opinion that a daughter is a blessing.

But how can an unborn child acquire a gift? This follows Rabbi Yossi's opinion that a fetus inherits and Rabbi Yochanan ben Berokah's opinion that a will made to the one who inherits is valid.
