I am having the same problem. My 5-yr old has a game going and i just went to check on them to make sure they were ok while she is at school. Didnt want her to come home and find her family dead as she was heartbroken when one of my characters died yesterday. I cured a few illnesses... fed them and made them sleep... but they are still in varying stages of "weak". Anyone have advice on how to fix the family?
