Babysitter Needed for my Children

We are looking for someone to attend a grown-up and me class with our 12-month-old son once a week for 1 hour (11:50am-12:50pm) while I attend a workout class next door. This would start as a once a week noon time slot and ideally progress to twice a week at 10 a.m. in a couple months. It is a fun class in a nice atmosphere that he is already comfortable in. He is a very active boy and needs someone who is comfortable with a busy 1-year-old.
