Don't die on me ;_;

I re downloaded virtual villagers and they're not breeding with each other and I only have two kids (thank god it's a boy and a girl) and omg. They'll die if they don't breed!! Help me :'(

It always says 'they're too hungry to think about this' and I make them bloody eat like 5 billion times and nothing is happening. Unless I have to do other shit to make them have more food (such as a fish supply) and omg. This has never happened to me before DD:

Someone save them!!! :'(
