How much detail should be put in a resume?

My wife left her last job in Dec 05. She started a new position in January, but then our daughter got sick and had a lot of doctor appts. My wife talked with her employer and decided it would be best for her to leave so she could take care of our daughter. Now we don't know if we should include this 2 month job on her resume or not. If we do, she may look like a job-hopper, but if we don't, it may look like she's falsifying a job application. Any employers or experienced interviewers have any advice?
