Babysitter Needed

I’m looking for a part-time Mother’s Helper to assist me with my 1-year-old and 4-year-old (both girls). I’m looking for someone who can help me through dinner and bedtime. I have a 17-year-old step daughter who stays with me primarily, but she is independent. I have two large dogs who are both very friendly. You must have your own transportation and be a non-smoker. I’m flexible and would like someone who can do most Fridays and Saturdays, but will give time off whenever needed.
