Harvest Moon: A Wonderful Life Special Edition Tips

Grade S Milk
When an animal loves you (all their hearts are filled in on the assets page) they give you the highest grade of milk, eggs, etc.

A faster way to get grade S milk out of your cows is to order good fodder. Only give your cow one good fodder a day, or it will get sick. Soon it will give you Grade S milks.

Hint: In summer, the milk will sometimes go down one grade because of the heat, especially if you bring your cows outside. If you have them at S rank, then you will at least get A rank through all summer.
