Read "The Female Brain" by Louann Brizendine, MD. I found it very informative. If you are a father with a young daughter, buy it now. Nicely covers the built in changes the human female brain goes through nearly continuously. Explains why a lot of emotional things happen, backed up with the scientific references. If you have decent reading comprehension, this is the closest thing you'll ever get to a "Owners Manual". Nicely compares and contrasts the similar changes in the human male. She decompiles the "source code" in a enjoyable manner.
Parental guidance advised, however. This is not exactly PG13.
