Hello Kaitlyn. I'm not sure which 3 games you're referring to but usually when the little families or villagers die it's due to untreated illnesses or lack of food, unless of course they are elderly. There is a wealth of information on the forums to get your games headed in the right direction. If you're playing Virtual Families or Virtual Families 2, there are links to helpful tips in this post. For a list of all of the LDW Forums click here or on the Forum List link at the top of this page.
