R.D.
We had a son and we both really wanted a girl the 2nd time around (terrible 1st pregnancy and could only think of doing it one more time). Anyway, it wouldn't have mattered either way but I found this ovulation calendar that also had an option to choose the sex. It worked for us but who really knows if it worked b/c of this.
