Part-Time (2x/week) Babysitter For 2 Happy, Fun Boys!

We are looking for someone to take care of our two boys (2yo and 4yo). looking for someone to help 2 days/week every week. I (Mom) am a part-time nurse working either Tues/Thurs or Thurs/Fri from 8-5, and my husband works from home but spends a decent amount of time traveling. We've been fortunate to have a wonderful babysitter taking care of our boys the past year+, and are looking forward to continuing to have someone who brings warmth and a genuine interest in not just watching our boys while we're at work, but also being an active participant in their growth and development. We're looking for someone who has their own transportation, does not smoke, and is flexible to expand their hours beyond 8-5 on days where my husband is traveling - could be 630-6 or 730-7 on those days. One 16-pound Goldendoodle, Goose! Very friendly and great with our boys.
