Harvest Moon: A Wonderful Life (PS2)

How to have a daughter
Go to the harvest sprites' house. In their home there is a pot in the back. Talk to the pot 100 times (you'll know you are there when the pot says "you win"). Talk to one of the three harvest sprites, they will ask you what your wish is, say that your wish is to have a daughter. Your child will be a girl instead of a boy. (Note: this must be done in the first chapter of the game)

Marry Lumina
To marry Lumina you must give her flowers of any kind. Also give her Moon Ores from the Dig Site. She likes both. As long as you give her one a day it does not matter which one you give her.

Son Or Daughter
At the end of the Chapter 1 you can choose between having a son or daughter.
