Bava Batra 141: It's Surely Worse to Be a Woman, But Go Support Your Daughters

When a man commits to giving an unborn child a set amount of money - regardless of the gender of the child, which apparently makes a difference in terms of the amount given - what is the halakhah? If a girl is supposed to get double the amount than the son, is she more valued than he would be? But the Gemara indicates that one who fathers only daughters is not in God's good graces. At the end of the day, providing for one's daughters in inheritance is upheld before one provides for one's sons. Also, one who is transferring ownership to a fetus is not successful in the transfer. Even though one can acquire goods on behalf of someone else, when one is not a fetus. Plus, a discussion of how various opinions line up with each other or don't - in this case, specifically probing that of Rabbi Meir.
