Sitter in Berkeley, California

I am finishing my sophomore year at UC Berkeley as a Neurobiology major. I will in the Bay Area the entire summer taking classes and am looking for a part-time job as a sitter in the evenings. I can provide my own transportation. I have spent the last year working in a Children's developmental psychology lab and am great around kids. I also have a little sister who is five years younger and spent a lot of time playing with her growing up. I am great with Barbies, dress-up, trains, and am a pretty decent cook as well. I have flexible hours and am reachable by telephone or email.
