I have babysat a few children ages 2 months-8 years. I watched the 2-month-old every day until he reached 5 years old. As far as training and experience goes, I haven't attended any babysitting classes, I just have a lot of hands on experience. I started out watching my cousin, his mom (my aunt) told her friends how good I was doing and they all started calling me. The most I've watched in a single sitting was 4 kids ages 4-9 months-7 years.
